Shortcuts Info-window

[Andreas Schmidt <andy rocket homelinux org>]

Hi,

just noticed a tiny UI-incoherency. When Balsa pops up an information  
window (e.g., if a signature could not be verified), there are two  
buttons: Clear and Close. Usually, pressing ALT-C will close the  
window; but in this case, both buttons have ALT-C as keyboard shortcut.  
Perhaps it would be better to map another shortcut to the Clear button?

Best regards,

Andreas
