Rename DOMApplicationCache to ApplicationCache and expose it to JS

Rename DOMApplicationCache to ApplicationCache and expose it to JavaScript
as per the latest specification:
http://www.whatwg.org/specs/web-apps/current-work/multipage/offline.html#applicationcache

This is particularly useful as ApplicationCache exposes constant values.
IE10 already exposes ApplicationCache to JavaScript while Firefox 23 does
not.
