If no main scene is defined, or if it's an empty string, the previous behaviour will still be used, i.e. launch the project manager.
A small fix was also added not to maximize the window when opening the project manager via -editor (i.e. "godot" and "godot -e" will behave the same when no project is in the path).
Fixes#2869.
Fixes#2611 which was a regression from 692216b86a.
The bogus behaviour considered that if there were more than one arguments left to parse,
they would be a pair of arguments (switch and its parameter), and thus skipped the next
argument in all cases (thus potentially skipping a "-editor", which triggered #2611).
This is fixed by checking first for arguments that don't expect a parameter, and only
afterwards for arguments that expect a parameter. And if a "pair" of arguments is not
valid, we no longer increment the counter.
-Visible 2D and 3D Shapes, Polygons, Tile collisions, etc.
-Visible Navmesh and Navpoly
-Visible collision contacts for 2D and 3D as a red point
-Customizable colors in project settings
A general speedup should be apparent, with even more peformance increase when compiling optimized.
WARNING: Tested and it seems to work, but if something breaks, please report.

Curse the day I decided to port UDP code, as it ended up
being two nights of work. At least It's done now (I hope).
-Fixed UDP Support, API seems stable
-Added UDP Chat demo (chat that can lose your packets, heh)
-Added helpers to areas and bodies to get list of collided bodies and contained bodies.
-Sped up screen/viewport capture code.
-Added code to save an image as PNG
-Small fix so scripts register their singletons after modules did.

Build System:
-Big clean up of SCons, changed how builds are done to a much cleaner method (check the Github Wiki for instructions).
-Deactivated BlackBerry10 (sorry), if no mantainer found (or BlackBerry does not send us a Passort ;), platform will be removed as we have no longer devices to test.
Engine:
-Removed deprecated object and scene format (was in there just for compatibility, not in use since a long time).
-Added ability to open scenes even if a node type was removed (will try to guess the closest type).
-Removed deprecated node types.
