MiniABS 1.2: Galician interface, larger text and touch targets

- Translate the interface to Galician (tools/translate_gl.py), including
  Galician month abbreviations for dates, which Android 2.3 lacks
- Resize for the Galaxy Mini's 240x320 screen: larger text, rows, tabs and
  buttons; all sizes now live in res/values/dimens.xml
- Redraw play/pause/refresh icons for every density; slightly brighter
  secondary text colours
