SystemUI heap monitor & hprof dump tile. 

Adding the tile to your active set will start a continuous memory tracker,
updating the tile every minute with the latest pss value. Tapping the tile
will pull a full heap dump, zip it, and share it via ACTION_SEND.

Additionally, @integer/watch_heap_limit can be set to the heap size (in KB)
at which ActivityManager will automatically generate a heap dump and notify
the user when it's ready.

Available only on IS_DEBUGGABLE builds. Supplies limited. Order now!
