SDL Controller Rumble Support

[FriskTheFallenHuman]

Describe the feature you want
Currently Dhemw3 does not have support for controller rumble, the only form of this is on events.cpp that is just this:

/*
================
Joystick Input Methods
================
*/
void Sys_SetRumble( int device, int low, int hi ) {
	// TODO: support multiple controllers.
	assert(device == 0);
	// TODO: support rumble maybe.
	assert(0);
}

What problem does it solve?
Lack of rumble for controllers, that is it

Additional information
Not sure if would be ideal to expose controller rumble to DoomScript? though would be nice to have
