Added option to manually copy+paste OAuth URL
Added option to manually copy+paste OAuth URL

Many Linux desktop environments do not support the Desktop.browse() method.
Added a simple fix to check if this action is supported, and if not, open a
dialog box allowing the user to manually copy the OAuth URL into their web
browser.
