Fixed offset bug in sign entities.
Existing signs' text will not be moved - this fix only applies to newly-placed signs (or at leasty, newly-spawned text entities e.g. after /clearobjects followed by punching). Also, made a few functions local that didn't really need to be global, some minor re-arranging of the code to accommodate the above and to tidy it up a bit.
