FlingTracker can divide by zero and hang StatusBar in an infinite loop

if 2 events have the same timestamp then FlingTracker in PanelView will divide
by zero causing NaNs. the bug is usually triggered by rapid StatusBar up/down
dragging activity and updateCarrierLabelVisibility can then loop indefinitely
looking at NaNs. the user visible symptom is that StatusBar refuses to pull
down and is burning cpu time.

Frameworks: TRDS new qualifier push up qualifier number (1/2)

Hey guys,

after this feature is working really well and a lot roms kanged
it we got a hint to change one thing which is indeed a good
idea to have less problems on AOSP updates and tools like
Apktool can provide us better without doing major changes every
AOSP update.

We pushed the number up to 69.....should be enough for
next years.

Please note for the one who are using our gapps at the moment
this will break actuall gapps till we published the new one
which will be end this week as usual.

After that we will begin to publish the apktool after we had
now enough tests....and who knows maybe the "official" Apktool
will provide us all now. So all in all a good time to change
the qualifier now before it is getting more and more
popular (we saw that first themes are providing us)

cheers

Lars
