finished centralization of query creation.

DatasetController.java: changed mapping for simplification
index.html: Changed option text also for simplification
main.js: replaced dedicated query methods for search, sort & filter with a central one, also refactored the url parameter generation process.

Also removed resolved TODOs and added comments
