wicd: fix dhclient interaction

wicd used to write dhclient config file into $out/var/lib/wicd directory attempting
to change nix-store. That didn't work and thats why we couldn't use dhclient.
With this patch wicd will generate temporary file name for this purpose. File is
generated each time the daemon starts.
wicd: bring translations back.
wicd: fix missing application icon

udisks: split to udisks1 (stays default) and udisks2
libgphoto2: update and add libxml2

HeavyWeight will be fixed after gnome3 from x-updates.
xfce: ./support/ not needed anymore
fix udisks2 paths
wicd: remove unused patches, remove ast with plain rm
gvfs: allow gvfs-network to access it's gconf schemas

gvfs-network fails to start until it stores some setting in Gconf (memory
backend is used by default). Unfortunately, it needs schemas for to work
correctly. By default, glib searches for schemas in /usr/share/glib-2.0/schemas
OR under GSETTINGS_SCHEMA_DIR. This patch sets this variable to let gvfs
find it's precious.
