Move PurpleIMConversation to its own file

Move PurpleIMConversation to it's own file.

Testing Done:
Compiled and was able to send an IM. It's not yet using `G_DECLARE_FINAL_TYPE` because `PurpleConversation` is not using `G_DECLARE_*` so it fails if I try to use it. I didn't clean up too much of the code yet, but I tried to get most of the formatting changes we have.
