Ticket text included in Incoming Messages

Hey all,

I've fixed some bugs, added new $bad* variables to block things, caught a few more error codes, and now messages by default (with $posttext set to 1) will also include the latest note on a ticket. For new tickets this will obviously be the first note.

Please let me know if you find any bugs or have comments/concerns. Ideally submit them to the issue tracker here on GitHub but feel free to message me on reddit as well or in the labtechgeek Slack chat if you're in there.

Thanks,
Joey
