Add support for git URIs

[doherty]

Like it says on the tin. Some git-ish URIs might better be represented as SSH (git@github.com:doherty/....git) or HTTP(S), but git:// should be it's own type, I think.

Seems a fairly reasonable idea; where's the specification? and which (if any) of the current URI types were you thinking about adapting for this?

[doherty]

I suspect that, like most of git, the spec is in the C code :\

[shadowcat-mst]

So I guess you'll have to experiment; it looks like a fairly straightforward host+path system mostly so build something using that, try it out, and then we can have a chat about how to torture test your work before it merges?

This is already out there, but it would be nice to merge that into the core URI distro. Though, @miyagawa would have to take it out of CPAN to prevent namespace conflicts.

@miyagawa would you like to merge this into the core URI dist?
