Shortcut subsystem

[antonydevanchi]

Need Angular2 Service which provide ability create shortcuts for application fast in a few lines of code. Ideal solution in pseudo-code looks like:

Shortcut('CmdOrCtrl+H', () => { // some logic }, false)

Corresponding third attribute also need create integration with Main Electron Process for creating global shortcuts (https://github.com/electron/electron/blob/master/docs/api/global-shortcut.md).
