gnome-panel strings change

[Sebastien Bacher]

Hi,

I've just uploaded a new gnome-panel changings some strings to the "add
to panel" dialog:
* "_Custom Application Launcher" has been changed to "Custom Application
_Launcher" to fix the accelerator conflict with _Cancel (#42037)
* "Select an _item to add to the drawer:" has been changed to "Select an
item to add to the drawer:", the accelerator was not looking nice and
doing nothing anyway
* "Search : " has been changed for "_Search: ", it fixes an incorrect
space and set an accelerator for the search feature


Cheers,

Sebastien Bacher
