* entity debug rendering, with command
needed to add getter method to MapEntity interface, so that's the reasoning for changing objects/npcs/player/etc
this currently brings allocs/s up to 10 (you can check by running `fps` command, se we need to look into d2debugutils and how it handles drawing text
* reverting velocity copy, broke the map entity tests. debug display wont show velocity currently.
* adding velocity debug
* Reorganize MapEngine
This is already turning into a mess...
* Map engine selects tile index to use
Still very ugly
* Fix subtile flag combination
* Prepare randomly generated base tiles
* Restore collision viewer
* Movement works again, searches for straight paths
Paths are now d2vector slices
* Fix LOS calculation
* Fix test (I think)
* Unnecessary constructor assignments removed.
* Position implemented in d2common.Path
* Position implemented in mapEntity.Step.
* Position implemented in d2common.PathTile.
