upgrade to latest mvdsv and ktx

[mushis]

summarize here the changes to make to the configs, regarding the updated ktx and mvdsv (qtv and qwfwd don't need? don't think so)

server.cfg

• add: set k_fb_enabled 0 //botmode whenever the map is reset (0=off)
• add: sv_demoDirAlt "" // alternative folder for demo storage
• change: sv_crypt_rcon 1

ktx.cfg

usermodes/matchless/ctf.cfg

• this commit

portxxx.cfg

• change: set k_use_matchless_dir x // use configs/usermodes/matchless instead of [...]/ffa (0 = no, 1 = yes, 2 = ctf)

Additional stuff:

• ensure ./upgrade_binaries.sh works ( sv-bin-x64.zip and sv-bin-x86.zip )
• ensure that the binaries are compiled in a machine with: pkg-config libcurl4-openssl-dev - even though it won't be used right now, these libs are needed to set www communitcation. source: https://gist.github.com/meag/09b7b6c736b8f2fde1df991cf1151abb

Did all of the above except for:

• portxxx.cfg - wasn't sure about this setting so leaving for now
• binaries are not compiled with libcurl4-openssl-dev as i could not get it to work with linux 32bit and, perhaps more importantly, i got an error saying it required the lib installed on the machine and failed silently when i installed it. Probably need to add a check for it in the installer in that case.

Rest of changes can be seen in nquakesv-changelog.txt among the distfiles on FTP (i'm also keeping a nquake-changelog.txt for client changes):
