Overhaul of the tap system so the keyboard does not cover up focused
inputs, correctly bring up the keyboard on text input focus, disabling
focus during scroll, disabling clicks after a hold then scroll,
removing 300ms delay without additional event handlers on each element,
etc. Refactored the tap/click/scroll/activator events for more
testability, along with adding more tests.
BREAKING CHANGE: The developer should be stating exactly how an icon
should show, but previously the right nav arrow icon violates this by
automatically showing a right arrow when an item was an anchor or
button. Instead of using the `:after` item selector, which was always
applied by default, it uses the same markup as `item-icon-right`, which
is easier to understand, customizable and not a hard coded default.
This change removes the `:after` nav icon styling, and creates a new
class, `icon-accessory`, based off of similar CSS. The change makes a
nav arrow highly customizable, allows RTL developers to easily control
the arrow direction, and the accessory class is something that's
reusable.
An example of right side arrow using `ion-chevron-right` as the icon:
<a class="item item-icon-right" href="#">
Check mail
<i class="icon ion-chevron-right icon-accessory"></i>
</a>
Main changes:
* Use gulpfile now (build was getting way too disorganized with custom
tasks; gulpfiles are much easier to build clean custom tasks with than
Grunt.
* View README#Development for updated commands
* Docs written for ionContent, ionHeaderBar, ionInfiniteScroll.
* Docs are pushed to ajoslin's fork of ionic-site until they reach a
* point where they can be published.
**TODO, In Order of Priority**
1. Finish writing source-documentation for all existing components
2. Add multiple versions of docs (one per release & nightly, latest
stable release docs being shown by default)
3. Add examples generation
4. Add searchbar to docs
