This commit adds two new aliases for the files associated with `framework.extras`. One to load the CSS (`framework.extras.css`) and for JS (`framework.extras.js`). Credit to @CptMeatball. Resolves#3909. Related: https://github.com/octobercms/docs/pull/334
The setTimeout fires after the modal already hides so it ends up firing twice which causes an error because the element is no longer there:
```
Uncaught TypeError: Cannot read property 'get' of null
at Popup.triggerEvent (storm-min.js?v443:3732)
at Popup.hide (storm-min.js?v443:3741)
at storm-min.js?v443:3730
```
Credit to @Teranode for the fix.
Since popovers and modals currently share the same z-index (600) a popover that gets created for a filter inside a modal is invisible. It is hidden below the modal. This commit adds a check to see if a filter is created from within a modal window. If yes, the popover will be added to the modal container. Otherwise the default container value `false` is used.

Adds action buttons ("Apply" & "Clear") to filter popups for UX improvement (past experience was click out of the popup to apply the selected filters and manually remove all applied filters). Credit to @Teranode. Fixes#3304.
This enables developers to modify what the cache key is for a given instance of a settings model so that they can do things like load user dependent settings values and have those values affect the rendered CSS. Previously the key being static across all instances of a given setting model would prevent that from being feasible without clearing the cache for every request.
This prevents an error from popping up after the popover is hidden/removed `this.$container.remove()` is no longer available after removal so we need to check for the presence of `this.$container`. Credit to @Teranode
Improves the System Status dashboard widget by adding a warning icon whenever the specific log is disabled. Credit to @gergo85. Thanks to @petehalverson for Octodock making testing easier.
Replaced the existing PNG flag icons with the flag-icon-css library that uses SVGs, has more flags, and is more active (i.e well maintained). Credit to @mariavilaro & @w20k. Thanks to @petehalverson for Octodock for easy testing of this.
If an email is seen (Message-ID:) then convert newlines to <br> unless within <html> tags. Also place the contents inside an iframe so the CSS rules don't leech out.
Fixes#3032
