Refactored the whole model generation schema (NavModelGenerator? is now AppModel?). Application model is only generated on demand by calling the AppModel?.sync method when going to the navigation controller (except on the console interface). This helps speed up web server initialization, scripts and automated tests.
Included system classes in AppModel?, including the new HyperDEConfiguration (in preparation for adding i18n support).
Fixed an old bug that used to leave garbage from other repositories (closes #18).
Added import/export for custom views (closes #49).
Fixed an old bug in the import script that would create duplicate context and index parameters. (It was caused by something deeper in the associations code). Closes #41.
