*Improved input recognition with information from the mailing list.

*A tool can now either match input perfectly, possibly or awful. So less options are displayed to the user (meaning the ChooseTool page can now be skipped most of the time).
*Improved layout.
*The Line Label at the bottom now show the name of the tool that's 'running'.
