Changed gui editor to show off and test the new tab features. Updated project files and makefile, have only tested vc8 and dev-cpp. Didn't know how to do the OSX project so I'll leave it for Dean. Moved EGUI_ALIGNMENT into separate header. Added getArea and getVolume for bounding boxes, no real reason for them. git-svn-id: http://svn.code.sf.net/p/irrlicht/code/trunk@1124 dfc29bdd-3216-0410-991c-e03cc46cb475
