Aw: Panel Settings Dialog (again)

[timystery at arcor.de]

i thought everybody was the opinion to not have a blown-up right click menu because of the resulting "remove me?" dialog, which some people do not like or will ignore or whatever and because of others not hitting the correct entry which would result in removing the item without a popup dialog.

Again, i suggest to add the "remove" button for each item to its properties dialog like it was before, where it surely won't be hit without reason. 

apart from that, i'm pretty much in favor for the "add new item" entry.
