RoomPosition.findClosestByPath ignores range option - always uses range 1

[SystemParadox]

The documentation for RoomPosition.findClosestByPath clearly states that any options from Room.findPath are accepted, one of which is range.

However, RoomPositition.findClosestByPath appears to ignore the range option entirely.

See https://github.com/screeps/engine/blob/master/src/game/rooms.js#L328. The range argument is always set to 1. It should be opts.range || 1.

This bug caused my creeps to not bother repairing structures which they couldn't get adjacent to, which is often the case with thick walls, blocking the observer behind other structures, etc.
