Fix application launch shortcuts.

Improved quick launch bookmarks to support category-based shortcuts
instead of hardcoding package and class names for all apps.

Added a set of Intent categories for typical applications on the
platform.

Added support for some of the HID application launch usages to
reduce reliance on quick launch for special purpose keys.  Some
keyboard vendors have hardcoded launch keys that synthesize
"Search + X" type key combos.  The goal is to encourage them
to stop doing this by implementing more of HID.
