In the future, hacketyhack shall work with shoes4. That's what we are working for.

However currently it uses the sqlite3 gem in `lib/database.rb', which is a problem because it needs c-extensions. That is a problem as jruby cut c-extension support.

From a first look it should be easy to replace sqlite with something else, I'd say Pstore or YAML::Store as the interface is tiny and well defined.

We would just have a problem with the migration of old user data. We could also use a jruby gem for sqlite3, if there is one. However, I'd much rather use the simple file based standard library functionality as mentioned above.

Thoughts?
