RFR 7902119: Add JemmySupport to jemmy/v3

[Alexandre (Shura) Iline]

Hi,

Could you kindly take a look on this integration. Along with the code I managed to introduce some minimal tests, because of which additional step is taken during test execution. Here is the sequence of steps taken when "ant test"n:
1. Source is compiled (from src dir)
2. Test data (from test_data dir) is compiled (into build/test_data) with Proccessor class as an annotation processor. These classes include a few Wrap class extensions and contain proper annotations. Generated sources are placed into build/test_docks. 
3. The generated source (from build/test_docks) is then also compiled  (into build/test_data).
4. Tests are compiled and run with  build/test_data in class path.
