Feature: Adding file types filter & F flag changed

-t = Show summary of types

-e = Filter by regex
	allows you to specify a file type like -e "\.txt$"

Change behaviour of '-f' flag - it now counts only files. Before it
counted files & directories. This was needed for compatibility with
the new '-e' filter flag
