Dark Mode support - Githubissues

Essential changes in order to support dark mode (iOS13+)

Replaced hardcoded white background with systemBackground in all xibs.
Enabled templating for all icon assets
Enabled custom tinting of the Schibsted logo in order to allow matching the barTintColor colour override.
Removed unnecessary resizing of the show/hide password icon in order to support tinting.
Tweaked a few individual components that didn't need to change colour in dark mode.
