Refactoring & Block Statistics Display

Moved thigns around so the package names make more sense now.
Decoupled the task of actually displaying things to delegate methods.
Added standard block changelist display delegate
Added new block statistics display delegate.
    This will display change/add ratios of all block types contained in a changeset.
    Pretty much like the change-statistics git prints out for non-binary files.
    Best used with area lookups (which have yet to be fixed)
Little addition to Statistics formatter
Bringing RadiusLookup up-to-date

So this should, in theory, work now.
