Change the meaning of holdsToken(): now the token(s) specified must be

EXACTLY held. I think this is ok because all callers currently pass a single
token at a time, but I have not verified this for every project.
Please verify this for your project!
Added holdsAnyToken() which has the old behavior of returning true if any
bit is on.

I think we should change all the projects' various isSupportPlus() methods
to be just called isSupport() and those will return
holdsAnyToken(SUPPORT | ADMIN | etc);
If you need to check if a user has a single SUPPORT token but is not an
admin, you can do that by hand.
