Main Menu Quantal amd64

[Ralf Mardorf]

Hi :)

Settings > Main Menu doesn't work correctly.
When I replaced the Ubuntu Studio HDSPmixer icon by the original
HDSPmixer Icon it worked, but when I tried to change the position of
Galculator in the Accessory menu, it didn't work. I deleted Galculator
and Gcalctool and add them again, but now both will only be shown in
the menu Other. I want both, Galculator and Gcalctool one below the
other in the menu Accessories, what ever they are named.
However, I reinstlled both calculators, but I didn't get back the
entries in the menue Accessories. Since I decided now to rename Gcaltool
from Calculator to Gcalctool the order wouldn't be an issue anymore,
but now they are both in the wrong menu. 

Regards,
Ralf
