v0.2.3 V-tables, better animations

This version controls 3D browser based animations via a command-line interface. This interface does not have any auto-completion.
Supported AIs are only table based: Q-tables and (more efficient) V-tables.
While code for Neural network based AIs exists, they don't seem to learn anything -> code has been disabled.

After this version, older version will no longer be included in the repository. They were a relic of me not trusting git.
