feat(mcv): add Military Conflict: Vietnam server config (#148)

* feat(mcv): add Military Conflict: Vietnam server config

Add server.cfg for Military Conflict: Vietnam (appid 1136190).
Source engine game using CS:GO-style parameters.

* fix(mcv): add mapcyclefile and document sv_hibernate_zombie_mode

Add mapcyclefile setting (confirmed by community - works like CS:GO).
Document sv_hibernate_zombie_mode which is unique to MCV - spawns bots
when server is empty to keep it active in the server browser.
