History limit removes the newest command, not the oldest

[RReverser]

This:

local-echo/lib/HistoryController.js

Lines 22 to 24 in 8d0b7f5

	if (this.entries.length > this.size) {
	this.entries.pop(0);
	}

should've been using .shift(). Instead, current behaviour keeps pushing one item into the history and immediately popping it back, so that once limit is reached, no history items are stored.
