* add: Freezetag gametype added.

Two standard modes, "FTEU" and "FTUS". Players are frozen until thawed by a teammate.
Callvote "thawtime" controls how long it takes to thaw.
Callvote "thawauto" controls time before players autothaw.

* add: Demo playback menu - shows all netdemos.

To playback most demos, "Enforce Files" must be turned ON (demo_enforcefs 1 or 2)
"Force media only" (demo_enforcefs 1) will play the demo with all the paks it was recorded with BUT using the latest Q4Max game code (instead of the version the demo was recorded with).
"Force all paks" (demo_enforcefs 2) will play it with all paks - including game code it was recorded with (instead of the latest game code).
Q4Max 0.75 can play most demos recorded with 0.74a and 0.74b except for TDM demos, which must be played back using "Force all paks".
If all required files are not present, the filenames and checksums will be displayed - if more than 1 is missing, they will all be listed on the console.
Support will not be provided for errors encountered using "Enforce Files - OFF". As usual, if there's something odd in playback, enforcefs 2 is a safe way out.

* add: Player Profiles.

Some competitions do not allow cvars not editable via the gui to be used. Player profiles are restricted .cfg's that may only contain settings that can be adjusted via the gui.
The cfg's can be saved and loaded via the menu interface or via the loadProfile / saveProfile commands.
When loaded via these commands or the user interface, no "restricted" cvar can be changed, allowing this menu to be used to load configs in competitions.

* add: CPMA style duel scoreboard.

Shows stats for both players, and a layout more suited to 1v1.

* add: "Net" now displayed in the TDM scoreboard.

* add: Callvote modelsounds 1 enables strogg sounds on all strogg models.

Applies a full soundset - pain, jumps, footsteps etc. Can be used with cg_enemymodel "strogg" or similar to get enemy sounds.

* add: autorecord command records a netdemo with a name in the same format as autoaction recorded demos.

* add: Client XML stats include "damagegiven" and "damagetaken" values
