Engine: * Forgot to commit hwengine.rc Training Missions: * Small tweaks to keep the time left once the goal is reached

-- Hedgewars Bazooka Training
-- Scripting Example

-- Lines such as this one are comments - they are ignored
-- by the game, no matter what kind of text is in there.
-- It's also possible to place a comment after some real
-- instruction as you see below. In short, everything
-- following "--" is ignored.
