rolling back the rest

rolling back (most of) lua 5.2 compatibility patches. hopefully that will unbreak unC0Rr's lua issues for now.

sekret feature (test commit)

- Increase limits on number of mines and explosives in game scheme - Stop trying to place mines/explosives after 4 fails to place in row

Drawn maps optimizer - first steps: - Break paths into segments

Merge

don't search for lua 5.1 anymore

Don't activate invulnerability/vampirism between shots of multiattack weapon

minimal changes for compatibility with lua 5.2, thanks to v4hn for fixing standard library loads. note: ALSO compatibile with (internal) lua 5.1, until something bothers to upgrade bundled lua version

Fix typo leading to crashes

Add race type detection

- Fix bug with infinite rounds in racer when a team quits mid-game - Don't allow placing waypoint right on top of previous one, prevents accidental double waypoints - Don't limit maps on number of embedded waypoints

No more occasional long straight edges

Spelling corrections

Optimize out path closing point for one point paths
