jPivot integrated into the Web application.

- Created a new database from scratch, filled with lots of fake data. Script made.
- Made a new script for the DW as well.
- Made a better landing page for jPivot, called `better.jsp`.
- Integrated the new jpivot route in the Web app (as an `iframe`), referencing `better.jsp?query=mallAnalysis`.
- Few bugfixes.
