Backport SmartInterval, PrettyTime, SubbableResource from EE.

## What does this MR do?

Backports infrastructure used for EE-only Timetracking so it can be used and improved upon in CE. 

This doesn't really need review... it was already reviewed and merged in EE. 

There are no side effects or conflicts, just three new classes added:

1. `SubbableResource` -- pubsub for ajax resources
2. `SmartInterval`-- for configurable polling
3. `PrettyTime` -- time parsing and formatting utility methods

Make milestone page responsive

Credit to @yury-n for this one. ⭐ 🌟 ⭐  Original MR: !5255

## What does this MR do?

> Makes the milestone page more mobile friendly

## Are there points in the code the reviewer needs to double check?

> Shouldn't be but maybe double check that the views I changed are exclusively used by the milestone details page I was amending and not any other pages that I haven't tested after my changes.

Looks good to me. :) Would be awesome to have @annabeldunstone check up on the stylesheet updates.

## Why was this MR needed?

> Buttons were misaligned

> Progress bar was not 100% width

> Stats were cut in the middle

> Milestone name/date text overflow

Resolve "Activity entries are not loaded fully to cover full window's height"

## What does this MR do?

Fixes a bug in which a browser window large enough to encompass the default number of items in an auto-loading endless-scroll list could not trigger the loading of additional items.

## Are there points in the code the reviewer needs to double check?

I refactored activities.js and pager.js into es6 syntax while I was investigating the issue.  No changes were made other than some es6 flourishes and eslint conformity, so nothing should be effected, but perhaps best to double check other pages which utilize these scripts.

## Screenshots (if relevant)
