crystallonlevels.xls improvements

LevelData.xml can now be constructed from data in crystallonlevels.xls
csv2levels_ALL.bat builds all the level xmls, runs the full solutions
analysis script, and the generates the LevelData.xml
csv2levels_LevelData_ONLY runs only the LevelData.xml updating script,
so things like the colors and sounds can be updated more quickly.
Also, I tried adding an Export macro to the .xls, which I will remove if
it doesn't work correctly.
