[2/2] Add bluetooth triggers to profiles

Change-Id: I374cc93364c88b8b29c88345deccf297234ff624
QS: Don't assume observers are registered when dealing with changes

Not all uri activity has an associated content observer. Poking
the content://settings/system provider manually, for example,
would result in the following NPE:

AndroidRuntime: FATAL EXCEPTION: main
AndroidRuntime: java.lang.NullPointerException
AndroidRuntime:        at com.android.systemui.statusbar.phone.QuickSettingsController$QuickSettingsObserver.onChange(QuickSettingsController.java:354)
AndroidRuntime:        at android.database.ContentObserver$NotificationRunnable.run(ContentObserver.java:180)
AndroidRuntime:        at android.os.Handler.handleCallback(Handler.java:725)

WebSettings: Move CM tag to the end of the user-agent

Append it at the end of everything to make it less obtrusive to
agent parsers, and append the CM device identifier so we can present
smarter choices when our sites are accessed.
