Remove links to timeline and machines view (1032470)

This work addresses Bugzilla bug [1032470](https://bugzilla.mozilla.org/show_bug.cgi?id=1032470).

As per discussion on IRC, it seemed the simplest method of suppressing the UI in the template, rather than trying to target injected elements with an ng-hide, or new css class on an nth-child() of the parent. We could try the ng-hide though if you feel it is a better approach.

I've added a comment in the code for ease of re-introduction later.

Adding @jeads and @camd for visibility.
