Spinner component lacks many properites #211

Brought up in the dev forum by @EnisM and @fturbak
https://groups.google.com/forum/#!topic/app-inventor-dev/VZ37e9sOPuM

The Spinner needs properties added:

⦁ enabled

⦁ background color

⦁ font bold/italic/size/typeface/color

⦁ text alignment

⦁ height

⦁ BeforeSelecting event and handler

The most critical is probably the BeforeSelecting handler, which will allow elements to be set when the Spinner is pressed. The ListPicker has this feature.

BTW, #132 needs to be done as well when these other items are added, or before. That's a pretty annoying issue too...
