widget icons don't use theme colors

[forrestguice]

The sunrise/sunset/noon icons aren't themeable (sunrise/sunset theme colors are ignored by icons). v0.5.0

[forrestguice]

Implemented w/ v0.5.1 but only fixes problem for api 19+. For lower versions the sunrise/sunset icons still fail to apply the colors (but the noon icon is fixed).

The sunrise/sunset icons are InsetDrawable (wrapping a GradientDrawable), while the noon icon is a plain GradientDrawable. Applying the colors to InsetDrawable requires getting a reference to the wrapped drawable, but (apparently) InsetDrawable.getDrawable() was added api19 (and for lower versions there is no access).

So there doesn't seem to be an easy fix w/out reworking the rise/set icons. Using a layer-list drawable instead might be a possible solution (or might suffer from same problem as InsetDrawable). needs research.

v0.5.2 fixes this problem for api21, api23 (relates to #126).

LayerDrawable (layer-list) does seem to be the solution. The recently added moon phase icons (using layer-list) are successfully themed on api15. ..needs more testing, especially later api versions.
