Make print command more useful. Ability to suppress normal text output

[rbnpi]

Sonic-Pi has a print command (eg print n or print "hello" ) that can be used to output text or variables. It would be of more use if you included a command to suppress the normal text output, otherwise it scrolls off the screen too quickly to be of use.

Version 2.0 allows you to turn off output printing in a preference pane :-)
