Posting a solution, dialog boxes

The code for posting a solution is up and running. I created a couple
schemas for dialogue boxes, we should all use these for consistency.
Cleaned up some random other files. NOTE: we still need to contact
question services on startup and on exit.. i did not add code for this
yet, but will on next commit (posting questions)
