Using the new Infusion lib and the composite/conditional panels. In some artefacts there are different PCP/PMT versions of them. This is because the PCP has a simpler version of some adjusters. Whenever possible, PMT version is extending the PCP version to avoid duplicated code. Also, there exists a helper PCP schema with these adjusters for Alex's convenience (src/shared/schemas/js/adjusters_364_365_forPCPSchema.js).

There are still some deprecated files that need to be cleaned up. Some translations are missing.
