S-Jog

hi there

I can fix these, by the way, just let me verify that
they are bugs for others as well:

1. vauge error messages (must be root to use
setbrightness), could give better info if the
setbrightness code was in sjog not in a separate utility.

2. click goes through to window manager: on my box the
click goes right through to the window manager (e.g. if
the mouse is on mozilla and i hit the jog, mozilla gets
a middle click and sjog also pops up the menu.

i'll fix em if you like...
