[WIP] Windows support

After adding windows ansible support to phpDocumentator2 @erikaheidi asked for my help doing this with Phansible (https://github.com/phpDocumentor/phpDocumentor2/pull/1355#issuecomment-49793145). After some [tweets](https://twitter.com/erikaheidi/status/492261781575061504) we've decided to do a living PR.

For now I've only updated the templates and haven't done any work on the site systems, until it's clear how exactly we want this to work.

Kudo's to @frenkynet for showing me this in the past.
