Quick Settings : Fix Sound tile

This commit removes the deprecated VIBRATE related code and uses
the proper 4.x api/settings to toggle the ringer states.  It also
now shows the proper state on reboot.

Patchset 2 : Remove deprecated (non functioning) VIBRATE_IN_SILENT

Port wimax support changes from CM9.

- Register WiMax service in ContextImpl (fixes 4G toggle).
- Fix misdocumented EXTRA_4G_STATE in WimaxManagerConstants.
- Share wimaxClassLoader between WimaxHelper and ConnectivityService.
- Add ACCESS_4G_RADIO_DISABLE, ACCESS_4G_STATE, and CHANGE_4G_STATE
  permissions to SystemUI.

Note that WimaxManagerConstants was previously misdocumented, confabulating
the lookup key EXTRA_4G_STATE ("4g_state") with EXTRA_WIMAX_STATUS
("wimax_status"), which no longer exists.  This is also fixed.
