FW : Allow user selection of Font Size

ps 1:  This re-structures a lot of the way icons & layouts are sized.
It allows System Icons, Notification Icons, etc. to scale according
to the size of the statusbar.  StatusBar now sizes itself based on
the height of the Font (which is user selectable in RC).

This needs a lot of testing, as I've made substantial changes to the
way the Statusbar.  Also, While everything is 'working', the alignment
of the Textviews alludes me.  All textviews are being aligned at the bottom
of the StatusBar rather than centering like they should.

PS 2:  Fix the issue with StatusBar robbing touches at boot.
Fixed windowing size update in PhoneWindowManager.
Some of the icons still don't scale exactly right,
and of course the TextViews continue to taunt me.

ps 3: Re write some of the scaling of images and add some padding.
   Create a StatusBarHelpers sub in core.util.aokp for re-using some routines.

ps 4:  Solved initial sizing issue (at boot or change) and everything
	seems to be aligned properly.
	Note that icons will only scale up to their source size.  So
	themes that provide HQ/large icons can benefit from larger
	font sizes, but some themes (including stock/system) will
	show increases in fonts and Notification Icons, but not
	the SystemIcons (right side)

ps 5: Adjust layout to elimination notification cutoff

ps 6:  Really fix layout this time.
