OnUnload() doesn't actually seem to get called, ever, so I added
an ifdef'd out line to the message send function that would save
the cache every single time the user sent a message. It works, but
eugh... my poor SSD works hard. I want to give it a break.
It doesn't actually happen for me. I rewrote GetCurrentLine() to
be more consistent with the rest of the codebase about newlines,
hopefully this will work for everyone.
