Add alias to `meta` and `metaRight` to make OS agnostic

[gossi]

I was wondering whether to use a meta key for the shortcut, which responds to cmd on mac rsp. windows on win and "super" on linux. The javascript KeyEvent already supports the meta key.

We have it setup to map the keycodes for command and window keys to:

• windowLeft/cmd – keycode 91
• windowRight/cmdRight – keycode 92

Source: https://github.com/IcarusWorks/ember-key-manager/blob/master/addon/utils/key-codes.js#L74-L77

So you can use either the windows or mac naming in your code and the mapping should work.

Does that answer what you need?

Ah yes, I didn't compare the keycodes. Nevertheless I think adding meta as alias is good. Using only win or mac terminology doesn't make the code look os-independent.

@gossi fwiw this was released in 0.1.5
