Imported a variant of http://code.google.com/p/android-color-picker/ into k-9
- Ported to the ColorPickerDialog API - Translated the API and Internals from Indonesian to English - Moved to use K-9 strings rather than custom strings. In an ideal world, we should use ambilwarna as an android library project, like it was intended.
