Messages get cleaned up when you save

When you save messages, we had some issues with some special characters and emoji symbols.

Now, when you save your message in the puzzle transaction threads, the system first saves your message to the database but then it reads the message back to make sure nothing got lost during the save. If what you sent doesn't match what gets read back, we stop the save process and display an error massage to you.

The system will also show you what got saved so you can review it. If you fix the message or simply approve the automated changes, the new text will get saved and checked again.

This feature was added because a user discovered that some special characters caused part of the message to not be saved. We don't want your messages to be altered without you being aware of the changes. This isn't a perfect solution, but at least if you are sending something we can't easily save, you will know what is going on.
