Added support for underline (#5)
Reading some more in the pinentry protocol [1], underscore followed by
a character means underline that character. To escape that two
underscore is used. Added that behavior in the messages. The input to
dmenu i.e the buttons, does not support pango markup so just removing
the underscore.
