(svn r2372) - Fix (console): update the example scripts in the scripts/ directory to reflect the new console functionality
- Fix (console): any line starting with a '#' is a comment so ignore it
- Fix (console): The special variables whose value can only be set by a custom process should, also print out their newly set value there, instead of relying on the default printout which is slightly confusing. Eg after you change the value it still printed out 'current value for...' instead of 'XXX changed to...'
