Added helpstrings, .* to rule regex

willie seems to prepend an implicit beginning-of-string character to each of the @rule regular expressions. For example, "blah is a heretic" would match, while "something something and blah is a heretic" would not match. Adding .* to the beginning should allow this to work as desired.

Added an example invocation to .heretic, and added helpstrings to the .heretic and .heretics commands.
