REFACTOR: Moved data type caster into its own function
Added 'json' data type which auto converts from a TEXT string in a DB field into a JSON object
Added support for string cast types
Added UnCast type method to convert types back to DB format, added fallback CastType which just returns source
enfoceTypes flag now also runs incomming data via UnCastType()
Re-added previously removed RequesterWants("put-json") meta request
ID requests in database WHERE conditions now auto apply table prefix to work around joining by similar ID problem in triggers
BUGFIX: Pretty major issue where allowget/allowset would get mixed up during a set operation
