new debug command to clear all monsters from the level
Direction flow was getting messed up in the second Proving Grounds level. From there onward, 'up' is going deeper into the dungeon so its entrance tunnel needed a down special space, not an up.
Adding Robot Grand Central node to cyberspace
Robots now have individual serial numbers.
Built basic menu for robot hacking
Camera state now handle via the LevelManager class
Created a new method is_toxic() for TerrainTile that returns whether or
not stepping on the tile will potentially damage the agent. (This is to
avoid a circular reference to Terrain.py from Agent.py and
LevelManager.py)
Merge branch 'robot-hacking' of github.com:DanaL/crashRun into robot-hacking
