FirefoxOS Marketplace can not validate the manifest.webapp

[FedericoElles]

I went to
https://marketplace.firefox.com/developers/validator
and entered your manifest:
http://robnyman.github.io/Firefox-OS-Boilerplate-App/manifest.webapp
which resulted in:

Your app failed validation with 1 error and 2 message(s).
launch_path must be a path relative to app's origin.
60x60px icon should be provided for Firefox OS.
App name may be truncated on Firefox OS devices.

It is because it has been adapted to running packaged apps in the Firefox OS Simulator. The launch_patch will be relative for how you will be using it.
