Fix crash in tag panels dialog.
External sdcard related cleanup.

We now show the user a dialog if they try to move to one of the
external sdcard app data directories. The purpose of it is to
warn them that uninstalling or clearing data for the app will
clear all their Quran data. Fixes #392.
Resolve toolbar issues on 2.3. Fixes #398.

- modified onMeasure to send an exact width/height to the pip,
since the old way caused getMeasuredWidth and getMeasuredHeight
to return strange values.
- replaced translate methods with offset methods on 2.3 and below.
the offset methods move the view, and thus, view clicks work as
expected, as does removing visibility.
- removed nineoldandroids since we were only using it for translate
on 2.x.
Update tablet detection logic.

Since some 2.3 phones would detect as tablet, changed the logic
such that tablet is only enabled for xlarge, sw600dp, and sw720dp.
