STCN-based Picarta scraping is working again.
A quick cleanup operation makes sure that most stuff that used to work works in the new situation as well.
What is new in this overhoul:
  * Works with the upped PGC.
  * Richer schema.
  * Richer documentation integration.
  * Less code.
  * Phrase from file uses a DCG grammar for the entire redactiebladen parse.
  * Works with the new, DCG-based ISO standards for languages, language families, and countries.

* [KMC_1200,SC] Updated Picarta code to the new situation.
* [STCN_CLEAN,SC] Combined with some operations that used to be in scraping.
* [STCN_LOAD,SC] Removed, since no longer needed.
* [STCN_SCRAPE,SC] Big cleanup operation.
* [STCN_WEB,STCN_STATISTICS,SC] Quick cleanup to make most of this stuff work again.
