Clean up 'no-tokenize' function... or replace with better implementation

[krayzpipes]

The '--no-tokenize' switch is not intuitive. It was originally designed so that tokenization happens by default (set in the default configuration). It's also a lie... it's masking, not tokenization.

Make the following changes:

• Remove the '--no-tokenize' switch and setting.
• Make a '--mask' or '-m' switch with the matching setting, and do not mask by default. Require the switch to implement the mask.
