Objects should have default values (or more sensible ones). Some examples include:
size of the most objects from AE seems to be 24x24, editor creates them with size of 40x40
objects dependant on variables should not default to 0, which is a hard-coded "off"
most new collisions will probably be used for walls/ceillings/floors, so Next/Next 2/Previous/Previous 2 should all default to 1 (otherwise they seem to behave weirdly)
doors default to the wipe effect "Play 1 FMV"
doors could default to the current level - in case of AE it's currently Barracks (although I don't think it's possible with the current design of the API?)
Kinda related to AliveTeam/alive_reversing#1644 .
