Banshee's last.fm plugin does not state what is needed to log in

Binary package hint: banshee

Steps to reproduce:
When using the banshee last.fm plugin, the user is asked in the preferences, to provide a username. Then there is a 'login' button. Pressing this button leads to it beeing replaced by two buttons, 'Finish loggin in' and 'Try again'. There is also text: 'You need to allow Banshee access to your Last.fm account'.

Problem:
There is nowhere a sign that tells me that when I pressed 'Log in' the last.fm page was opened in my webbrowser (which I can't see, since it is on a different desktop) and is waiting for input from the user.

Fix:
Replace the text: 'You need to allow Banshee access to your Last.fm account'.
with something meaningful like: "The last.fm page was opened in your browser. On that page you can give Banshee the right to access last.fm" or something like this
