This allows nodes to be pulled from git repositories that:
1. Require authentication
2. Are located on a computer that does not have any special software
beyond an SSH server to serve up git repos
3. Are hosted on sites that exclusively allow SSH access
I have also cleaned up the JavaScript regex for identifying valid HTTP
addresses. Due to an unescaped '.' and the lack of a count on the first
group, it wasn't doing a whole lot anyway -- just checking that the very
first character wasn't invalid.
