resolution support fix/improvement
* adding compatibility menu
* backup gravity
* set expanable=true if the screen size is hvga * density.
* added "supports any density" mode. I'll add sdk check later.
* disallow to catch orientation change event if the app is not expandable. This
was causing layout problem under non-expandable mode. I discussed this with Mike C
and we agreed to do this approach for now. We'll revisit if this causes problem to
a lot of applications.
