Remove dockmanager from Archive, 15.10+

[Bryan Quigley]

Source packages: dockmanager
Binary: dockmanager, dockmanager-daemon, python-dockmanager
(bryan@desktop:~$ apt-cache showsrc dockmanager | grep Binary)

Remove from 15.10 if possible, if not 16.04.

Created dockmanager specific bug from https://bugs.launchpad.net/ubuntu/+source/glade-3/+bug/1496227.

Justification: Checked with last uploader and makes sense to remove dockmanager. it also mentions it's no longer supported here - https://launchpad.net/dockmanager

Note about docky (see reverse recommends below):
docky is actively maintained in both debian/ubuntu
https://packages.debian.org/sid/docky still has a recommends to dockmanager even though it doesn't exist there. Dockmanager is not available in any current releases of Debian.
