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.
