Slashes unescaping seemed overcomplicated.

I think we're seeing the end of it.

Apache don't really like escaped slashes in the <path> part of the URI. They have a config option to support it though, but it's [disabled by default](https://httpd.apache.org/docs/2.2/mod/core.html#allowencodedslashes).

This commit simplifies the fix #64 :smile:
