Revert "Try markup in TimeItem with Spans"

Since we can do color highlighting (and alignment) in both TextViews.
This reverts commit 27aa7a43cff3fb3f604bc197a0994025c4bbcc73.
Use 2 TextViews as Spinner item
Text markup in TimeSpinner and cleanups
Rewrite Adapter and Android Studio updates

PickerSpinnerAdapter doesn't make use of the super.getView and getDropdownView any more. Works perfectly now, only need to finalize the twin_text_item and twin_text_dropdown_item with the correct layout and text markups.
Updated Android Studio to 0.8.1 beta, but still running on old SDK and build tools (v19) until they are stable.
Add @LayoutRes annotation in various places
Simplify PickerSpinnerAdapter and use right dropDownResource
Layout adjustment in dropDown Menu
Update sample with listener+Toast
Very stupid fixes to DateSpinner
