Backported warnings cleanups from head
itw itself warning cleanup: fixed rawtypes and unchecks, added braces and Override
unittests warning cleanup: fixed typechecks, rawtypes, redundant casts...
ScreenFinder fixed to work partially also in headless mode
kept comaptible with jdk6
After this clean up only "internal proprietary API and may be removed in a future release" warnings remain fro make check. Please keep itw in this way :)
