Increased jump-height (and other changes) in version 0.9.5!

A new version of the demo has been uploaded: version 0.9.5.

This build includes a number of changes:

• Increased jump-height, and with it jump-distance.
• A few traversal changes in Chapter Two related to the new jump-height, including a new minor traversal section.
• Various security updates.
  
  • In particular, the language files should now be safe!
    • (I still don't recommend taking files from strangers in general, of course.)
• The fixing of some memory leaks.
• Miscellaneous minor fixes and changes.
