0.4.1

Added

• Mental rotation example

Fixed

• Require keywords to be matched on word boundaries (turn autokwd feature of
  textX). The problem was that keywords are recognized if being start of the
  larger word (like or in orientation).
• Consider component parameter non-constant if it contains message
  sub-expression. Constant param expressions are set on the component before the
  test run and are not changed afterwards. The bug was that expression like
  1..100 choose would be treated as constant although a new random value
  should be calculated for each trial.

Changed
