Reviewed by Ryosuke Niwa.

Source/WebCore: 

IndieUI is a new W3C spec that aims to abstract the connection between input and action, so that
a user (possibly using assistive technologies like a screen reader) does not need a specific kind
of device (like a mouse) to interact with an object.
http://www.w3.org/WAI/IndieUI/

This initial patch adds in the basic support for UIRequestEvent and the uiactions attribute.
It modifies the config files to enable and build this feature.
