Various Patches
setup for Castle boost

add new variables and saveData
(Castles).bought to .totalBuilt

alter previous Molpy.casltesBuilt to (Castles).bought so they point to
.totalBuilt instead
see:
https://github.com/eternaldensity/Sandcastle-Builder/commit/225a657282bb4a7c61dcf732674372596dfaafec

should solve many if not all of the castle shop issues
remove (Castle).spent undefined checks

no longer needed as spent is defined on creation now
