Minor grammar, spelling and contextual changes

I absolutely LOVE what you have done with the Date and the Timer stuff.
My involvement in SugarCube had waned only because "LIFE" got in the way.  I  am back to dedicate time to helping with this and ALL of the RubyMotion universe.
This is just the first contribution I can make to SugarCube.


If you do not mind, I provided myself credit for the "center" Adjust set of code.
