Do not load the demo game by default
Moved the assets to folders inside demo/

The reason is that files in assets/ get copied to the root of the jar. Putting them in folders makes it easy to unzip just those directories.
Minor fix for the default transcript contents
Added autogenerated files to .gitignore
Initial commit of the work on new tools
Merge branch 'new-tools' of github.com:raydeejay/escape-game into new-tools
