Better text results, tracks opened filename, added "Save As" to new file and updated ScintillaNET.dll

I hope I checked in everything that is needed to build the updated version.  If not please let me know.  I have made some changes that I think are useful.

- Text Output now outputs all columns (tab delimited) and result sets.
- Opened file name is cached and used when doing a save.
- Save As added to file menu to save updates to a new file.
