"Clear all" button on recent apps
Highlight the clear button in the recents view when clicked

This commit also makes copies of the ic_notify drawables for the recents
panel to avoid any collisions with possible future changes to the
notification bar UI. (The pressed state drawable was already an unused

ResolverActivity: don't use Holo Light
GlobalActions: Fix possible race condition when showing dialog.

Depending on the presence of a previous dialog, the newly generated one
gets either immediately displayed (no old dialog) or shortly delayed
(after dismissal of the existing one).
If a new show event happens (by rapid fire of the power key, for instance,
using a keyboard with fast-repeating events) during that delay, a new
dialog will be immediately displayed, and when the delayed show triggers
it'll conflict with it (and bring everything down).

This moves the creation of the new Dialog object to _before_ showing
it (delayed or not), instead of the show method itself, to ensure the
object isn't clobbered by competing/sequential calls to handleShow()
