config-repos: Error when running generate command with local path as source

[jrfnl]

After #3, I edited the generator.xml.dist file to contain the following:

<?xml version="1.0" encoding="UTF-8"?>
<generator format="markdown">
    <source path="D:\000_GitHub\PHPCS\PHPCompatibility\PHPCompatibility">
        <standard path="PHPCompatibility" />
    </source>
</generator>

Using the config-repos branch, I then tried to run the following command again from the root of this repository:

$ php ./bin/phpcsdocs generate

And got the following error response:

Searching for sniffs in D:\000_GitHub\PHPCS\PHPCompatibility\PHPCompatibility/PHPCompatibility/...

In NotASniffPath.php line 18:

  The file path provided does not follow the convention for a sniff class.
  Must contain {Standard}/Sniffs/{Category}/{SniffName}Sniff.php
  Received: D:\000_GitHub\PHPCS\PHPCompatibility\PHPCompatibility/PHPCompatibility/Sniffs/Classes\ForbiddenExtendingFinalClassSniff.php


generate [<sniff>]

I suspect this may be due to the multiple PHPCompatibility directories in the path ?

On second look, it doesn't appear to have anything to do with the multiple PHPCompatibility directories, rather with the mixed Windows/Unix slashes in the path.

Looks like some slash normalization is needed for cross-OS compatibility.
