New selecting/deselecting

[Kilinich]

I'm completely dislike selecting/deselecting methods of 1.7.5, I think classic Phun/Algodoo 1.6 was fine.
Here it is an example:

1) Select all circles by encircling
2) Try to add box to current selection (with Ctrl I suppose)

OMG, that's just too anoying for words.
This really need to be changed, I haven't got this "selecting hell" before but I think it would become really anoying.

The new rule is:
ctrl to add/remove from selection (xor).
shift to remove from selection.
ctrl+shift to add to selection.

So everything is still possible. And if you prefer the old behavior: "App.GUI.ctrlSelection = false;".

The reason for the change it is easier on beginners (ctrl most often both selects and deselects, see windows explorer file selection, for instance).
