InWorldz Halcyon 0.9.40 R6779

This update only addresses a couple of things needed immediately in InWorldz, and a few things we already had queued for the next release:

• Fixed object deserializing to avoid dumping binary assets to the console on an error. (This may fix the long-standing problem of an unattended XOFF causing the console to hang, requiring manual intervention.)
• Fixed saveportable oar to allow an empty list of UUIDs as per help and the rest of the function is coded.
• Fixed a null reference exception in mesh uploads and other assets when no money module.
• Fix issue #418: Invoke the code to check and apply a fee on group creation if configured
• Only apply the fee and message if the group is successfully created.
• Report group create failure to user. Fix typo in success message.
• Enable Ubuntu builds on AppVeyor
