Subject: Refactor plugin loading for WinRT

Specify the root directory to be the package root. Only plugins
inside the root can be opened (actually also only files). Furthermore
current defaults to the package root now, which in most cases is
identical to previous behavior.

When attempting to load a plugin the path can either be specified in
host format "C:/..." or as plugin absolute "/platforms/...". Check for
both, with preference of latter case, like when qt.conf is used with
/ being used as plugin path.
