Add candamage, hostile and projectilehit to getentityproperty.
Allow interger value for the three in changeentityproperty, by having the highest bit set. This makes property copying easier.
For example, changeentityproperty(self, "hostile", openborconstant("TYPE_ENEMY")+openborconstant("TYPE_NPC")+0x80000000);
