Fixed automap_addnextmap not working correct, thanks for X-Coder's report.

New update before new year.

Added:
* New convar sv_automap_advertise - enable/disable addon advertise in game chat (with commands for vote etc).

Fixed:
* Command automap_startmapvote start vote with extend option when write it like "automap_startmapvote 1" (and now will be without extend option in this case).
* Command automap_setextend not working correct.

New update - new features by requests!


Added:
* New convar sv_automap_blocktime - how long should be blocked vote for nextmap just after previous vote. Default 180 seconds (3 minutes).
* New convar sv_automap_loadtime - how long should be blocked vote for nextmap just after map loaded. Default 300 seconds (5 minutes).
* Console command automap_abort - allow abort change map from server console.
* Console command automap_reload_cycle and automap_reload_settings - reload map cycle or settings (convars) without changing map.

Updated:
* Renamed convar sv_automap_minvotes to sv_automap_minmaps for better understand what it is. Value can be now from 1 to 9.
* Renamed console command addnextmap to automap_addnextmap.
* Renamed console commands admin_startmapvote and admin_setextend to automap_startmapvote and automap_setextend.

Fixed:
* Text out of hud size when there is long map name or gamemode.
* Small other improvements and fixes.

Small fix for "addnextmap" command.

Fixed missing font error.
