[maven-release-plugin] prepare for next development iteration
Put Scroller in package that only matches this library.
Javadoc fixes.
Add methods for getting the menu and content containers.
Deprecate MenuDrawerManager.
Renamed everything 'width' to 'size' in preparation for top drawer:

 - A number of protected/private fields in MenuDrawer has been renamed
   accordingly.
 - MenuDrawer.setMenuWidth and MenuDrawer.setDropShadowWidth has been
   deprecated and replaced by setMenuSize/setDropShadowSize.
 - Styleable attributes mdMenuWidth and mdDropShadowWidth has also been
   superseded by mdMenuSize and mdDropShadowSize.
 - Styles used in the samples have been updated.
Added support for placing the menu drawer at the top:

 - HorizontalMenuDrawer is a specialization of MenuDrawer specializing
   measure and touch events for revealing the menu at the top or bottom.
 - TopDrawer implements layout and manipulation of a menu placed at the
   top.
 - Added TopMenuSample activity showing it in action.
Support indicator in TopDrawer.
Implement indicator for active view in top drawer.
Fix forcefully generating hardware layer on JB.
Move the menu view outside the screen when drawer is closed.

On older platforms where hardware layers are not used, simply toggle
visibility. This prevents overdraw, and ensures that the hardware layer is
created on start-up.
Bump build target.
Allow usage of drawer in layout files.
Avoid rounding errors when slowly dragging.
Remove MenuListView, it wasn't needed.
Check API level before enabling hardware layers.
Only use hardware layers on API12+.
Change package.
Remove deprecated class.
Allow custom touch bezel size.
