Added initialise button and core-collapses
Fork service now does a GET and sets attribute forked to false if this
this returns a 404
Initialise button shows if not forked
Corrected size of initialise button
Repo not displayed if fork load failed
When Initialise clicked, initialising displayed and event fired,
which is caught by tick-card which logs to console
Added functionality to fork button
