Provide .zip or .tar.gz release

In order to package this application on ArchLinux, it's better to have a tar.gz release or .zip one. This can be done automatically using gulp I guess.
Thanks!

Pull request is welcomed.

electron-builder supports the pacman format. Is this it? Google shows it is a package manager used in ArchLinux.

@ewnd9 never heard of that format before...is that a PKGBUILD file(it's the one used on Archlinux). Anyway, providing a .tar.gz or .zip file is better ;)
