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.
