msg_info - new sub for displaying messages
Define a new subroutine msg_info which prints messages to screen only if option{info} is true. No need to use the check to info flag ( $Options{info} && msg(...) ) every time something is to be displayed.

Also fix a few bugs, where message output was not properly suppressed with the --quiet option set.
