* Exploratory pass at adding support for macro params in filter operands
* whitspace correction

* Revised regular expression and removed spurious white space changes
* More whitespace cleanup and added more tests for edge cases
* Added test for macro params with square brackets
* wikirules now use better macrocall parser
Before, wikirules would use a deficient macrocall parser which couldn't
handle certain types of arguments. Now it uses the same one that the
widget parser uses. Less code!
* style changes and removing weird switch statement
That switch statement made more sense in an earlier iteration.
* comment improvements
* oops, wikirule macrocalls could do ONE thing better
* '=' wasn't allowed for widget macros, but why?
Now they're allowed for both widget macros and macrocall macros.
