Revised pre-defined incremental modes, as well as external mode filters that
are used to generate .chr files
Placed this script under cut-down BSD license
Added a script to (re-)generate all .chr files at once
Changed the default incremental mode names to ASCII and LM_ASCII
Update for new pre-defined incremental modes
Revised the wordlist rule example to use the "A" command instead of appending
two characters one by one
Documented the 'q' key
List 'q' before Ctrl-C in the help message, because 'q' is friendly to AMD APP
SDK and AMD GPU drivers, whereas Ctrl-C is not.  This is relevant in -jumbo.
