Gmod tickrate and fix for many maps

Fixes https://github.com/dgibbs64/linuxgsm/issues/685
Tickrate needs to be lowered in order to be able to handle a large amount of players.
Default tickrate is 66.66, but the -tickrate commnand will round numbers to the lower integer. So i'll default at 66 and not -the more accurate- 67 to not worry anyone with a "non standard" value.

For the +r_hunkalloclightmaps 0, it fixes the hunk overflow crash on server startup when using maps with too much lights (and there are a lot of them). It changes the way lights are stored in RAM, the 0 mode (default one a few years ago, and still default one on clients) can handle a way larger amount of lights, but a theoretically a bit slower way. I noticed no difference, so it's a good thing to fix it by default.
