Fix Pelican rendering and unit tests on Windows.

* Fix {filename} links on Windows.
  Otherwise '{filename}/foo/bar.jpg' doesn't work
* Clean up relative Posix path handling in contents.
* Use Posix paths in readers
* Environment for Popen must be strs, not unicodes.
* Ignore Git CRLF warnings.
* Replace CRLFs with LFs in inputs on Windows.
* Fix importer tests
* Fix test_contents
* Fix one last backslash in paginated output
* Skip the remaining failing locale tests on Windows.
* Document the use of forward slashes on Windows.
* Add some Fabric and ghp-import notes
