use bootstrap-tab-history to pop tab switches onto history

[DaanVanVugt]

Summary of changes

• Automatically switch to anchored tags on load
• Push tab switches onto history

Motivation and context

I'd like to be able to deeplink to the calendar / map views

Note that we'd need to update that tab since it only loads the calendar once we click (and I expect the map to behave the same?)

Does this still avoid #671 ?

We used to have a tab memory feature but it did not behave well with turbolinks

[DaanVanVugt]

This should add to the history set, so I don't think it would cause that problem.

I checked just now, but the search page does not use the tab helper so has no memory.

Looks good otherwise
