+ new API methods
+ some code refactoring

You can scroll them either with mouse wheel, or by pressing <> buttons. I have set parsing from "updates.md" — it's a markdown file, where ---- is a separator for news.

Actually, renamed system wrapper class Twig to Kotwig.

/coursework/create — create new coursework
/discipline/create — create new discipline
/discipline/127 & /discipline/127/structure — edit the discipline with id 127
/discipline/127/students — edit the list of attached to discipline students

Moved duplicate code to before() method, some other refactorings.
