Update 0.503c

Update 0.503c fixes a major issue with not allowing users to sign on and some other minor bugs.

Bug fixes:

• Fixed start screen hanging when creating a password that was not at least 8 characters

• Fixed broken buoyancy for objects in meditations

• Removed references to get mass for world object as this must be done through air magic now
