longDistanceHarvester struggles in rooms with more than one source

[rfsjim]

Long Distance Harvesters need a better way to be issued with source, as current sourceId using array index [0] seems to switch between sources in a multi source room, making the harvesters move between source objects. Suggest could simply use full sourceID as a saved memory item for the room.

var source = creep.room.find(FIND_SOURCES)[creep.memory.sourceIndex];

	// if creep is supposed to harvest energy from source
	else {
	// if in target room
	if (creep.room.name == creep.memory.target) {
	// find source
	var source = creep.room.find(FIND_SOURCES)[creep.memory.sourceIndex];
	// try to harvest energy, if the source is not in range
	if (creep.harvest(source) == ERR_NOT_IN_RANGE) {
	// move towards the source
	creep.moveTo(source);
	}
