Credit to @ayumihamsaki. Fixes#4400.
- Added WAI-ARIA to the layout templates files.

- Added WAI-ARIA to tabs and created keyboard arrow controls for tabs.
- Added event.key polyfill to allow removal of deprecated event.keyCode, event.charCode and event.which.
- Fixed all the whitespace, tabbing and indent issues with all the lang files.
- Keyboard navigation now allows the following key actions: Tab, Up Arrow, Down Arrow, Left Arrow, Right Arrow, Home and End buttons.
- Added keyboard navigation for tab panels.
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.
Use native scroll on mobile devices (much better UX)
Stack settings menu items 2 column medium, 3 column large
The settings search is now forcibly focused
This should make Windows PCs look a little nicer, albeit inconsistent with others (Sergoe UI is unique). If it's good enough for GitHub, then it's good enough for October.
All text shadows have been stripped, along with some box shading. They were barely noticeable and should speed up the UI.
