First release of phpIP

Since the software has been in production since 2011, and includes many fixes and enhancements since then, it is high time to create a release. So here goes. I'm not tagging it v1.0, because a few enhancements have been included since the first production use in 2011.

Included is a virtual machine for VirtualBox (1.25 GB), based on Ubuntu 16.04. Import the VM into VirtualBox and launch it. You should be logged-in automatically to a minimal Ubuntu Unity interface (if not, login with phpip/phpip). Open FireFox - it is configured with http://phpip.local as the home page - and use the credentials (saved) of the Installation guide.
