WebDAV does not show Media virtual folder
Error response is 404.
The bug has appeared after introducing eZURLAliasML (probably)
The reason is very simple - new url alias systems does not force nice url to be lowercase, but WebDAV module still tries to access it using lowercase "/media" path instead of "/Media"

Steps to reproduce

setup ezpublish-3.10.0beta1 with plain_site.ezpkg,
set in webdav.ini

[GeneralSettings]
EnableWebDAV=true

and try to access folder \plain_site_user\Media
