ignore patterns and pdepends/phpmd and Windows

[auroraeosrose]

Pdepends and phpmd have a really painful method of doing ignores

they use the same filter class for their file and then PIPE IT THROUGH REGEX (oh, ick)

https://github.com/pdepend/pdepend/blob/master/src/main/php/PDepend/Input/ExcludePathFilter.php

This makes the current method of creating ignore rules complete break on windows (where filesystemiterator will give you back backslashes to compare against) and makes ignore directories a pain because you need both a singular (ignore /vendor) and plural (ignore vendor/*) to work right

I have a pretty horrible hacked up fixed for this at

https://github.com/auroraeosrose/phpqa/blob/powershell_works/src/IgnoredPaths.php#L28
and
https://github.com/auroraeosrose/phpqa/blob/powershell_works/src/IgnoredPaths.php#L54

it's not entirely ideal (I should have pulled them out into a base helper method that each calls) and it still needs file level support added but it works to do ignores properly

But without some sort of a fix ignores are completely non-usable on windows for these two tools
