+ GUI CHANGES
+ BROKEN IMPLEMENTATION FOR NODE CONTEXTMENU AND VARWATCH
+ VarWatch kinda works now.
Moving to MVC design. *KINDA*. -Thanks DarkLotus
Fixed return value for parent Node class, Constant nodes which does not have a Process() method were returning 0, now they should return their set value instead of changing it to 0.
Modified Addition node to accept more than 2 inputs, can't think of a good reason not to do so. (At least for this kind of node).
Giving proper format & cleaning out some null spaces.
