The message boxes that tell you that the browser is initializing or that
you're authenticating with twitch are annoying on startup. It makes
sense to do it in the settings/autoconfig dialogs where you sort of need

it's not really necessary and can be kind of annoying.
Adds a function for initializing browser and cookies in a separate
thread while, and while waiting for it to complete, show a dialog
stating that the browser is currently being loaded. Allows the ability
to safely prevent the user from taking any action without actually
freezing up the UI thread.
Allows the ability to switch cookies between profiles. Allows the
ability to, for example, switch streaming service accounts between
profiles for proper access to the pages displayed by the browser panels
(such as chat windows).
