Log Message:
teeworlds: Update to 0.7.5

An exploit was discovered, that allows to crash any 0.7 Teeworlds server.
Though it does not compromise the security of the host (e.g. no arbitrary
accesses in memory) it lets an attacker force a server to repetitively shut
down (CVE-2020-12066).

The 0.7.5 release is a security update that aims to patch this server
exploit. As such, it is very light in features, and is mostly made of fixes.
