OCSADV-173: Integration of ITC web app into odb.

An (almost) fully functional port of ITC to odb. "Almost" because this PR contains only the source code and not the data files (876 files, 1GB uncompressed text data; this results in a jar file with 200MB). Comiting this PR and the data into the develop branch would leave us with an ITC web app fully integrated in the odb infrastructure taking advantage of the PAX war extender.

This PR does not address the issue of making ITC available without the credentials however this is a solvable problem by providing a dummy credentials file. If we decide to go along with this I would also double check dependencies and jar files etc. to make sure that we add only the minimal set of stuff.
