38f85c98b5 Fix 3267 Add "onHover" functionality for legend (#3271) 
Add "onHover" to the legend options that will hold a user defined function (default is null) and called when a "mousemove" event is registered on top of a label item, with same parameters as the "onClick" option.

Also introduced logic that determines if the type of event passed to the legend "handleEvent" function is one we can handle. Currently allowing "click" and "mousemove" events. If the event is not one of those we stop the function execution (this is for the sake of reusing the legend hitbox calculations).

Suport minUnit for time scale

Suport minUnit for time scale 
When dealing with time-delineated datasets, often we have data for known
intervals of time. For example, we may have a dataset which represents number
of purchases per day:

```json
{
	labels: ['2016-01-01', '2016-01-02', '2016-01-03']
	datasets: [
		{
			data: [12, 87, 42]
		}
	],
	'...': '...'
}
```

In this case, Chart.js will attempt to figure out the best interval to display
the data, and could pick `hours` as the unit. However, in this case, we would
prefer to just use the `days` interval since our data's granularity can not be
represented well with `hours`.

To remedy this, this commit adds the `minUnit` option which allows
users to (optionally) specify what the minimum unit they would like
to use.

cd24895cd1 Build labelDiffs cache once per update (#3211) 
Previously buildLabelDiffs() was called at the end of buildTicks() and
hence labelDiffs cache was calculated twice (in getMinimumBoxSize() and
then in fitBox()).

69ab0d3e23 Use gulp-eslint instead of gulp-jshint 
Change the linter in gulp tasks to be consistent with Code Climate results which are based on ESLint using .eslintrc options. However, defaults Code Climate rules are too strict, so turn as warnings the 'complexity' and 'max-statements' rules (other errors has been fixed). Note that the Gulp task name has been changed for `gulp lint`.

6269e2c437 Error possible when using the plugin Chart.Zoom.js used with time scale (#3194) 
Zooming in can cause the params `datasetIndex` and `index` to be null in method `getLabelMoment`. This happens when no ticks are visible on scale. It also throws an error and the chart becomes broken.

c283867f73 Remove smallestLabelSeparation from TimeScale (#3186) 
In case of charts with over 4000 points, smallestLabelSeparation
calculation contributes significantly to total cpu usage (about 25% according
to built-in Chrome profiler). Important thing to note is that result
of this calculation is not used at all.

Related commits:
  * 677c249b61
    introduced smallestLabelSeparation. It was used in calculateBaseWidth
    function.
  * d198157fb8
    removed last use of smallestLabelSeparation. Since then the calculated
    value was never used.

Fix out of bounds index access in getLabelMoment 
Previously, calling getLabelMoment with an out of bound index would cause an
error such as this:

```
Uncaught TypeError: Cannot read property 'null' of undefined
```

This happens because there is not always guaranteed to be a labelMoment on
at the current datasetIndex.

One example of this is practice comes from a this function call:

```js
// since the are not always guaranteed to be at least two labelMoments
//                                \ / this index can be out of bounds
//                                 |
var tickWidth = me.getPixelForTick(1) - me.getPixelForTick(0) - 6;
```

This patch simply ensures that the `labelMoments` for the `datasetIndex` are
defined before accessing properties on it.

7a419af4c2 Rename plugin service and notification method 
Rename `Chart.pluginService` to `Chart.plugins` (so move the old Chart.plugins array as a private member of the service), and rename `notifyPlugins` to `notify` for consistency with other service methods.

77357e57d6 Refactor spanGaps for line graphs with sparse data (#2721) 
Fix #2435, this very slim patch (including its relevant documentation addition) adds a small option to line chart datasets (spanGaps) that allows users trying to graph sparse datasets to have lines between null entries drawn, rather than omitted.

287cefc9b9 Rewrite a few helpers to be more efficient 
Resolve at definition time if a browser built-in method or our polyfill should be used, so avoid checking it for each call. Also, `helpers.extend` doesn't need to iterate two times on the function arguments. Finally, remove helpers never referenced.

This change allows for smaller minified code in the final version, resulting in a smaller file size. Some files had previously used _this, but that has been changed to me to keep consistency throughout the project.

2bc8e3c7f6 This PR allows for multi-line labels, as per Slack discussion.. 
Usage: If a label is an `array` as opposed to a `string` i.e. `[["June","2015"], "July"]` then each element is treated as a seperate line. The appropriate calculations are made to determine the correct height and width, and rotation is still supported.

view samples/line-multiline-labels.html to see it working.
