Listen() does not work on OptionController more than once

[gvdvenis]

Just found out that this line below is breaking the listen() method on the OptionController

Try changing the value of the items in an attached array and notice that the control doesn't update its value. After commenting out this line everything works as expected

dat.gui/src/dat/controllers/OptionController.js

Line 79 in 8cd1b4d

if (dom.isActive(this.__select)) return this; // prevent number from updating if user is trying to manually update

A tricky one, since not updating an active option input would usually be desirable.

Pull request #224 addresses this issue, by passing true into listen(true), thereby forcing updateDisplay to bypass the active check. Also in my fork.
