HaikuDepot: Token Based Authentication

This switches the application over from using basic
authentication to using token-based authentication in
preparation for later using Open-ID based
authentication flows. The application version is also
bumped in order that the server can detect this version
at some later date in the future when it no longer
supports basic authentication itself.

HaikuDepot: Check User Auth on Start

The user might have changed their authentication details
on the server and the client won't detect this until
they go to do something. Instead, if possible, check
this as the client starts. Also check that the user has
agreed to the current user usage conditions.

As a side-effect this generalizes the logic for process
coordination in the main window and also fixes some bugs
in the main window's progress display as the application
starts.
