Game DLL expects gi.Args() return raw arguments, give it what it wants

for compatibility reasons (preserve non-ascii chars and double quotes in team chat, etc).
Added `addfiltercmd', `delfiltercmd' and `listfiltercmds' commands
designed to prevent game DLL from interpreting certain client commands.
