Replaces #4965. Rolls back #4895. Fixes#4964. Partially fixes#4819.
The previous attempts to add a stylised "focus" ring, while with the best intentions, did not take into account how "outline" normally works for people using visual aids. Most high contrast software will effect the outline if its available (ie. make it bolder or more prevalant), thus the "outline" property is paramount to maintaining accessibility.
The previous changes also present issues with elements using box-shadows already, and again, on high contrast, box-shadows are no longer rendered.
This change will bring back the outline property for focus, but with an addition to allow a blue highlight for Firefox, would should keep it in "parity" with WebKit.

It is unsure why this was ever needed, but it appears to fix the overflow issues with the sortable plugin

This is one step closer to fixing the sorting issues when a scrollbar is present. It still doesn't quite fix the issue, still need to find a way to get the container dimensions to update

If a website has a Service Worker installed it would load and register before a User tries to login to the backend causing a "Invalid security token" message. This PR unregisters any installed Service Worker when a User opens the backend Signin webpage.
I have also added the NEW Security Headers to add Protection to October's Cache and Cookies. This includes two new Middleware that first clears any bad cached data before a User tries to login and the second Middleware will clear all the sensitive User Data when a User signs out of the Backend.
For more info on the new Security Header 'Clear Site Data' you can see the spec found here: https://www.w3.org/TR/clear-site-data/Fixes#4076, fixes#3707.
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.
The removed css rule makes filelist entries unreadable on touchscreen clients
that also have default pointer input support. The entries have a blue background
with white text when hovered. By setting the background to transparent the
text is no longer readable. Credit to @tobias-kuendig
Adds the ability to specify an `ignoreTimezone: true` option on the config for a datepicker form widget or date column type. This will ignore both October's and the backend user's timezone settings to display the date exactly as it is stored.
