unity (6.2.0-0ubuntu1) quantal-proposed; urgency=low

[ Adam Conrad ]
* Removed debian/patches/libgeis-rename.patch

[ Łukasz 'sil2100' Zemczak ]
* debian/rules:
- added override for dh_shlibdeps to point it to the private directory of
libunity-protocol-private.so
* debian/unity.lintian-overrides,
debian/libunity-core-6.0-5.lintian-overrides:
- added override to silence the binary-or-shlib-defines-rpath error, since
we are forced to use RPATH in our case
