[ANN] v1.2 Online JavaScript Interpreter for Cat

[Christopher Diggins]

This is to announce that I have released version 1.2 of the online Cat
interpreter. There are some bug fixes (e.g. "dup" now properly copies
lists) and I have introduced primitive graphics capabilities, along
with a new tool-tip help text to the various predefined instructions.
Have fun, and feel free to reuse the source code, it is public domain!
