also cleaned up a bunch of little things in the bug report implementation:
- the abort had race conditions
- formatted the collections a little bit better (hopefully)
- broke the implementation up into multiple files
- fixed broken interaction with drracket (the drracket frame mixin is now being used properly)
- added the search string to the title of the window
- made the default preference includes scrbl files
- adjusted the title of the window to put drracket last
