Gradle migration

[smarek]

• to run application interactively: gradle run
• to run application tests: gradle tvgs
• to see dependencies: gradle dependencies
• to clean and rebuild: gradle clean build check
• to see debug info append -d after any gradle command

TS definitions moved to folder src/main/typesystem/, every definition must be compliant with pattern *_TS.xml

Thanks a lot! Currently lives in the gradle branch.

TODO items:

• Figure out the cause why YodaQA garbagecollects all the time when run from gradle but not when run from maven
• Update documentation (git grep mvn)
• Update curated-measure.sh
