Updated documentation. Some changes to Adabox.

* Updates documentation. Removed all tags (other than grouping) to allow easier
reading within GPS. Closes #18.
* Added Mouse_Tracking & associated enums.
* Removed Focus Tracking mode. May be added later, but currently conflicted with
Check_Mouse_Tracking, which is deemed more important.
* Removed some Adabox functions. These included functions that returned one of
the out parameters of another function.
