FOSS gamedev and creative worlds

based on kahrls stairs branch I've added object collision handling. I've only made it fully operational for luaentitys and player objects as items don't need it and c++ mobs are most likely to be removed.
LuaEntities do honor the "pysical" flag, collision handling is only done for physical = true.

It's only a proove of concept some changes need to be considered if there might be better solutions

Does this require Kahrls collision branch to work?

I will test it later so was just wondering.

this branch is based on kahrls so its already included.

Ah yeh sorry I didn't see your merge message when I checked earlier haha, just wasn't looking properly.

I've moved the getCollisionBox function from ActiveObject to a separate interface class this will reduce changes necessary
