Changes

* ''' Runtimes & Simulators ''': WebIDE supports Firefox OS devices connected via USB. It's also possible to install and run simulators.

* ''' Auto-install ADB ''': ADB (required to connect the phone via a USB cable) is automatically installed and controlled via WebIDE. The user won't need to install extra addons or android tools.

* ''' Key-bindings and quick iteration ''': Common keybindings make iterating very simple. Write code in WebIDE. Save (Ctrl-s). Push and reload app (Ctrl-r). Close app (Ctrl-w). Repeat.

* '''Device Info''': get an extensive list of data from the device (versions, hardware, screen resolution, permissions, ...)

* Debug Android tabs

* Manage simulators (install/uninstall)
