Stop DDOSing ourselves

## What does this MR do?

Adds `hiddenInterval` to `SmartInterval` settings. This will be the interval used whilst the tab is inactive. If this setting is not set it will `cancel` as it would have done before.

Adds `immediateExecution` to `SmartInterval` settings. This boolean will dictate whether to execute the callback once before the first interval or not.

Uses `SmartInterval` with the new `hiddenInterval` settings to slow the polling for the MR widget on inactive tabs.

Fixes issue where `SmartInterval`s `visibilitychange` listeners are not getting called because jQuery doesn't support them.

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

## Why was this MR needed?

We're ddosing ourselves on the MR page.
