Remove listenToAndRun

[dhritzkiv]

Since ampersand-view inherits from ampersand-state, which inherits from ampersand-events, which defines the listenToAndRun method, this definition in ampersand-view is no longer needed.

I believe the behaviour is the same, with the exception of the return value (returning this vs undefined in ampersand-events and ampersand-view, respectively) so it shouldn't be breaking.

However, there is an if statement in ampersand-events::listenToAndRun –and not in ampersand-view– which I can't seem to understand, and would like some help understanding:

listenToAndRun: function (obj, name, callback) {
   this.listenTo.apply(this, arguments);
   if (!callback && typeof name === 'object') callback = this; //<--this line
   callback.apply(this);
   return this;
}

Went ahead and searched through the commit history to find where this was added. Looks like the function hasn't changed since it was put in AmpersandJS/ampersand-events@9bb79f5#diff-0b121f2854b7a4eb5166c685e0f68ed1R170

It appears to have been in the predecessor to ampersand-event too from the very beginning https://github.com/n1k0/backbone-events-standalone/blob/master/backbone-events-standalone.js#L243

This means it was likely in backbone at the time, however it isn't anymore and I do not have the git skills to spelunk for that tonight.

I say once we get #154 ironed out we rebase this and if the tests still pass we ship.
