Optimization, fleshing out launch dialog.
Incremental commit to fix build error.
Removed illegible default HUD elements, added support for the
optimized Virtual Earth layer.
Added .xml spec for otpimized Virtual Earth layer.
Made significant improvements to build.xml, including integration with
Launch4J, so that the EXE will be rebuilt along with the rest of the
distribution.  Also updated the README and dev notes.
Somehow the Launch4J folder did not get through on last commit.
Updated Git and distribution READMEs
Added spaces to Git README so that it displayed better.
build.xml now actually builds the code.  also works now in linux.
