Modifying Styles

Updated Styles to show FPM instead of %
Added DependencyProperties to RadialGaugePiece

Added Maximum and Minimum DPs to RadialGaugePiece. Now can display
values anywhere between Minimum and Maximum by setting the Value. BUG:
Doesn't appear to be working with Maximum of 3000 at the moment
Mission Accomplished!

Got everything working as I want. Design could be cleaned up some, but
is manageable.
