Updates:

- 20-synaptics: this set is still not perfect, but getting better
- bashrc:remove an unused alias, add a new screen function
- gorilla: fix .desktop file
- screenrc: weird backspace corruption fix (don't use autowindow titles.
  it can affect the x session somehow.
- synclient-settings.sh: an easy way to apply all settings if they get
  lost at resume.  this stinks.  Now I have to maintain 2 files with
  same settings.  must fix.
- setup_new_*: updates
