Release 0.4.2

FEATURE - Show LOW / HIGH just like the dexcom when the value is 39 or 401
BUG FIX - Forecasting used the wrong values as the base when using the Colors Theme was used and the value is displayed as red.
PARTIAL FIX - The toolbar button shouldn't wrap as bad as they do in 0.4.1, but there might still be wrapping in some cases.  More cleanup later...
