Added status bar to utilities

Created by: agraubert

status bar is a simple scrolling progress indicator (with optional percentage display)

status bars also contain an internal display attribute which always represents the ideal state of it's output to stdout (if nothing else is printing to stdout, they will be the same)

The attribute can (and is) used for testing, but could also be used in situations where you may not want the status bar printing straight to stdout on its own.
