[vdr] vdradmin: patch for relative paths (apache mod_proxy)

[Matthias Weingart <matthias@pentax.boerde.de>]

To get the apache mod_proxy working (as described in another mail today
here) I patched the vdradmin_0.11 to use a relative path in the created html
files. All I tested is working; so this patch should be ok.
