Added docs build for grunt
Added infinite scrolling support for AJAX
Better infinite scroll

Only show the "No results found" message when there are no results
visible in the list. This avoid issues when loading more data, and
it returns no results.

Only try to see if the load more button is visible if it is present
in the DOM. This prevents making continuous requests when there are
no more results.
Fix AJAx example
Added matcher example and reworked compat

The matcher example now matches the old matcher example, and the
compatibility module has been turned into a function decorator
instead of a class decorator.
Rewrote the matcher example
Added Spanish translation and fixed the example
Started working on the initial release announcement
Convert array data to options immediately

This converts individual objects passed in through the `array`
parameter to `<option>` tags when Select2 is initialized. This
removes a lot of duplicate code from the `ArrayAdapter`, and keeps
everything closer to the native `<select>` element.

This introduces a breaking change from previous versions of Select2,
where the initial value for array data was blank, even if a blank
option was not present in the original array of objects. Now the
first object passed in will be selected by default, following the
behavior of a standard `<select>` element.

This breaking change does not affect `<select multiple="multiple">`
elements, which by default have no selection.
Added test to make sure the options are generated
Improve option generate speed

Now the options are mostly generated by hand before being passed
off to jQuery for templating. This fixes much of the speed issues
we had when they were entirely being generated through jQuery.
Improve data array speeds

This improves the speeds of creating the `<option>` tags for array
data. By creating the HTML ahead of time and putting it into an
`<option>` element before passing it to jQuery, it cuts down on the
time it takes for jQuery to process the HTML string and convert it
into DOM elements. This proved to be incredibly slow.

This also changes the `item` function to return early when the
data exists. The `$e.data` call has also been switched to a
`$.data` call, which doesn't need to check the DOM to see if the
data attributes already exist. This cuts down on a bit of wasted
time, as the `data` key should never be present in the DOM, and it
should be ignored if it is.
Fix caching when querying

This fixes caching when querying, so the data object no longer
needs to be completely regenerated whenever the `<option>` is
queried.

While this does not fix the speed issues on the first opening of
the instance, it does fix the speed issues during searching.
Remove jQuery from building the options

This fixes many of the speed issues the results had when working
with large data sets. jQuery has been completely dropped, with the
exception of setting the data, which does not require a jQuery
object but instead works directly with the DOM. This does not
include options with children, which still uses jQuery to deal
with the nested objects.

This only works with IE 8+, which is fine.
Fixed default selections for arrays
Automatically create options on select
Focus the search upon opening
Added default selection for AJAX
