Ping on unlock changes

 * Stop message flip animation on unlock
 * Prevent ping spam on unlock -
    - Ping ONLY if NEW notification received while device is locked/screen is off
      (If a notification pinged HALO once but was ignored, it will not ping again unless updated)
halo, bugfixes

1. fixed size for content
2. flip animations for tasking only
3. batch size calculations
4. not a bug but pinned and system both get the same icon for now

volumepanel

file is identical to cm's - i assume it crashes there, as well.
i'd rather take it out than bugfixing it - try/catch is silly but
seems to work for now
