panel handle size changed

[Jasper Huijsmans]

Hey,

I just updated CVS with some minor changes to the panel. From the log
message:

- Reduce handle width to show only one line of dots
- disable completion combo, because it doesn't work on new installs
- put 'Properties...' and 'Remove' in a submenu of panel item 
  right-click menus. May prevent some accidental removals.

Just thought I'd try and justify the spamming of the commits mailing
list ;-)
