nothing much.  Messed around, broke things, realized they were broken, undid my messing around, fixed them.
duplicating functionality in main.cpp, and modifying a few other files as needed to do so, got up to line 1646.
finished first cut on converting main.cpp to coloredAmounts. Also changed mining rewards, block intervals, etc.
duplicated and modified routines in wallet.cpp and wallet.h to work with coloredAmounts.  Some bugs in txout selection remain.
