Up the minimum Perl to 5.8.9.

Unicode worked differently in 5.6.  It'll be a pain to keep compatible with it
now that we support IDNAs.

For #4
Normalize the commenting which came in with the IDNA patch.
Remove URI::URL.  Support git scheme.

URI::URL::strict() has been replaced with a check to see if the URI object
is of type URI::_foreign which indicates a scheme URI does not understand.
This is a violation of encapsulation.  It's been very stable for years
now and I'm going with it for the time being.

Best solution would be to have our own list of schemes, but I don't
have an internet connection right now to handle that.

URI::URL would always use the canonical version.  URI stringifies to the
exact URL as written.  I think this is better, less loss of information.
You can always ask for the canonical version.  This might cause a
backwards compat problem for some users.

Added the git scheme as our first non-URI.pm supported scheme.
Document the changes and incompatibilities.
Merge pull request #6 from schwern/refactor/remove-URI-URL

Remove URI::URL
Remove a comment about URI::URL.

URI does not have this inconsistency.
Update the meta and INSTALL docs for Unicode and removing URI::URL.

Need an updated URI for unicode support.  Could probably get away with an
earlier release, but 1.60 is what's in Debian stable and that's a good measure.
Add reference documentation about URIs.

This will help folks develop URI::Find according to the spec.
Add support for svn, ssh and svn+ssh.

For rt.cpan.org 57490
Don't match hostless, pathless domains.

This is specifically for http://.  Can't just check for host because
some schemes (like file) have no host.

file:/// is valid because it's how you express the root directory.

For rt.cpan.org 63283
Add a --schemeless option to urifind.

This is convenient for users and makes it easier to casually test URI::Find::Schemeless.

Didn't make it a short option because I couldn't think of a good one.
All the short options should have long alternatives anyway.
