more icons

princess has an alternate > tiara if that is prefered (or it can be used
if there is ever a tiara upgrade I guess)
named gold icon 'money' since it includes silver

Didn't get to all of the missing ones, there are still quite a few that need done. Quite a few added, and I think I checked em all, but wouldn't hurt to double check me. If anything looks bad, doesn't fit the boost or whatever, let me know.
