Panel context menu

[Jannis Pohlmann]

Hey Jasper,

I jus talked to Fabian about the context menu. What we are sceptical
about is the fact that we've got some 'lingual overhead' in the menu:
"Item Preferences", "Panel Preferences", "Remove this Panel", etc.

Currently, we've got a kind of header in the context menu, which says
"Trennlinie" ("separator" in English, I guess). Wouldn't it be great to
group the different actions? For example:

	Item
	--------------------------
	Preferences
	Remove

	Panel
	--------------------------
	Preferences
	Manage Items
	Remove

	New Panel

	About the Xfce Panel

This would make descriptions shorter (and more readable in most
languages). What do you think?

Regards,
Jannis
