Console command execution and command text buffering.
Any number of commands can be added in a frame from several different
sources. Most commands come from either key bindings or console line input,
but entire text files can be execed.
Command execution takes a null terminated string, breaks it into tokens,
then searches for a command or variable that matches the first token.

idCommandLink is a convenient way to get a function registered as a
ConsoleCommand without having to add an explicit call to idCmdSystem->AddCommand() in a startup
function somewhere. Simply declare a static variable with the parameters and it will get
executed before main(). For example:
static idCommandLink sys_dumpMemory( "sys_dumpMemory", Sys_DumpMemory_f, "Walks the heap and reports stats" );

================================================
The CONSOLE_COMMAND macro is an even easier way to create a console command by
automatically generating the idCommandLink variable, and it also allows all the
command code to be stripped from a build with a single define. For example:
CONSOLE_COMMAND( Sys_DumpMemory, "Walks the heap and reports stats" ) {
// do stuff
}
NOTE: All CONSOLE_COMMANDs will be stripped with the shipping build unless it's
created using the CONSOLE_COMMAND_SHIP macro.
