timelimit_override broken (only works for gametype dm)
The timelimit_override cvar does not work in any gamemode, except dm.
Example steps to reproduce:
g_ca 1
chmap stormkeep
// timelimit 20, as expected
timelimit_override 15
chmap stormkeep
// timelimit 20, should be 15
g_tdm 1
chmap stormkeep
// timelimit 20, should be 15
g_dm 1
chmap stormkeep
// timelimit 15, timelimit has changed to 15
g_tdm 1
chmap stormkeep
// timelimit 20, timelimit has changed to 20, should still be 15
