changed layout of Counter and FadeCounter

Revised code in both Activities when it made sence to do so with changing the layouts.
Will probably need to move the reset display methods to a utility class because so many
will be reused from Counter in FadeCounter
added xlarge layout resources, worked on view stats layout
added basic shared prefs

User can set the difficulty level to one of three choices. The accelerator is set at the beginning
of the game based on the persisted prefference.  Still need to add in a way to dynamically change
the difficulty level during a game.
Added dynamic difficulty switching.

Now if the Shared Prefs difficulty setting is changed, the accelerator is set to
what is would be had the user been playing the entired time on the difficulty
aetting.  Now the reading of incoming intents needs to be worked on in Counter
Activity, the level is increasing if the user navigates away from the activity
to change the difficulty or view the game stats.  It should stay the same.  Going
to mack a Debug branch for this and math bugs.
