No need to hack the client, the server is enough (aka libcod). 
The player vote kick menu is sending ClientCommand's, which can be pre-processed and then ignored (so no vote will be called, just "return" out of callback).
Code for _callbacksetup.gsc:
PHP Code:
CodeCallback_PlayerCommand(args)
{
output = "";
for (i=0; i<args.size; i++)
output += args[i] + ", ";
printf("PLAYER COMMAND! message=\"%\"\n", output);
//self iprintlnbold("you wrote: " + output);
args = fixChatArgs(args);
// ...
// ...
// ...
Output:
Code:
PLAYER COMMAND! message="mr, 32, 1, axis, "
PLAYER COMMAND! message="mr, 32, 3, kar98k_mp, "
PLAYER COMMAND! message="mr, 32, 0, callvote, "
PLAYER COMMAND! message="callvote, tempBanUser, kung, "
