android: Add buttons to increase/decrease indent

This adds two buttons to the formatting toolbar to
increase/decrease the indent, using the corresponding
UNO commands. These can be used when the experimental
editing mode for Android Viewer is enabled.

The drawable resources were created using the
corresponding sifr_svg icons (incrementindent.svg,
decrementindent.svg).
