Sanitise Bluetooth file name hint when receiving a contact 

If a contact name is entered with any of the following characters

  :"<>*?|\n\t

the transfer of that contact fails.  This is due to the underlying
filesystem (FAT) not being able to handle these characters in a
file name.  This fix corrects that situation by replacing any
whitespace characters with a space and illegal FAT filesystem
characters with underscore.
