Clean up buttons on channel page

Click on an individual channel name on the dashboard page (currently still under this URL on staging: http://qa-vumi.za.prk-host.net/channels/)

The user is directed to an individual channel page: http://qa-vumi.za.prk-host.net/channels/xmpp_vumigo_solo%3Axmpp-solo-0001/

We need to clean the buttons up on this page. See screen shot.
