Summary:	Implemented screws 436 and 437. Major changes to implementation.

	SCR 436	We implement caching at three different level to improve performance. Caching data from the database (this also makes the web application less vulnerable to database connection losses). Server-side caching of generated pages. This is a real improvement. Client-side page caching (the server asks the client's browser to cache pages for a while).
	SCR 437	On the schedule page, the GPS and GCDE patterns can be clicked on to show the pattern details. This information will now also available for HEX, 5x5 and custom dither patterns.

The current version of the web application needs to be restarted every time the connection with the database is gone. We changed this such that the database connection is restored automatically (when possible).
Another change is that the new web application will only show revolutions for which the POS has actually been sent.
Technical comment: we no longer use the JBuilder data access objects. Instead a whole new framework is introduced using Spring, Hibernate, EHCache and Ant.
