RFR 7902144: Make jemmy/v3 build/test with Maven

[Erik Greijus]

Hello all,

Please have a look and get back with comments on this change.

Description:
Currently jemmy/v3 is built and tested by means of ant scripts. As such dependency management is manual and can be an obstacle for new developers. 
Setting the project up with Maven makes it more or less plug'n'play (as long as the user has installed Maven).
