Rur-ple 0.9.8.2 released

I implemented in rur-ple the "auto-indent" feature that was added to Lightning Compiler. This should be more user-friendly for beginners. I also fixed a bug that was introduced when I improved the highlighting method - it was no longer possible to run programs where robots were introduced by an instruction [e.g. Reeborg = UsedRobot()] in an otherwise empty world.
