Here's a new update on SyntaxHighlighting goodie.
This one incorporates Helge's updates from Apr 26,
and does a more radical migration to syntax highlighting:
instead of changing all methods that call #makeSelectorBoldIn: and
#askIfAddStyle:req:, these methods are changed to call either their
original versions or the syntax highlighting code (driven by the
Preferences browseWithPrettyPrint).

A reminder: this is Helge Horch's work, I just tweaked it to work with
Squeak 3.1.
