Keyboard shortcuts conflict in text inputs

[oskarrough]

It's not yet working as it should. player keyboard shortcuts are triggering inside (some) inputs.

This is still a problem in #298

It happens when we use the normal <input>. When we use Ember's {{input}}, the keyboard events don't trigger more than they should.

So… to close this issue we have to make sure that the shortcuts defined in https://github.com/internet4000/radio4000/blob/master/app/mixins/keyboard-shortcuts-global.js DO NOT trigger inside either <input> or {{input}}.
