In Gnome and Unity desktop (and maybe some others) this can be used to open a new Code window through right click on the launcher icon and then on "New Window".
.rpm packages can now be build with:
gulp vscode-linux-<arch>-build-rpm
The resulting package will be output to ~/rpmbuild/RPMS/<arch>/ and can be
installed on a Red Hat-based distro with:
yum localinstall <path>
Note that Debian systems can build the package after installing the 'rpm'
package:
apt-get install rpm
This was tested building 64-bit on Ubuntu 15.10 and installing on CentOS 7.
Fixes#3595
