Add RewriteController to allow easy handling of historic rewrites

[nhp]

Added a new controller to be able to access the old rewrites vsf-api knows nothing about. It simply makes a DB call to core_url_rewrite, filtered by request_path and returns only the new final target.

Usage

Simply called by /vsbridge/rewrite/target?request_path=old_url this returns {"code":200,"result":"target_path"}

As we agreed with Łukasz Romanowicz on slack we should bring this functionality to the main magento1 trunk.

Also added store_id handling as this could also be an issue and we added more specific result-status codes to reflect on what really was the problem instead of only returning 200 and especially 500.

Do we still have open issues here?

@ResuBaka hi! any update on the PR changes?

[ResuBaka]

I will update in the next days.

The problem is that I need to send the request URLs html encoded.
