Render debug info in tactical

Functionality for rendering pathfinding and cover values in tactical was behind defunct #ifdefs.
It's now compiled always, but only enabled if cheat level is BEDUG_CHEAT_LEVEL.
Unified rendering the debug info into one function, instead of several nearly identical ones.
Ctrl + Shift + Z cycles through the different debug modes.

Now it should be fairly easy to add more info modes like these two in the future.
