[ANN] Conditional Tags Extension v0.2


I just released v0.2 of the extension. Changes include:

* Jeff's request for a "status" evaluator.  The term "status" gets
  evaluated into a string ("draft", "reviewed", "published", or
  "hidden").  Keep these requests coming.
* And I beefed up (fixed) the mechanism for other extensions to
  register their own evaluators.  I'll be releasing another
  extension shortly that will demonstrate how to register your own
  symbolic element evaluators for use in conditional statements.
