[windup-dev] Let's use relative paths

Hi, I suggest we use relative paths. For the reports, using full paths may get overly verbose and make the reports unreadable. Relative paths are usually not, that much. Compare e.g.: INFO: Unzipping /home/ondra/work/Migration/Windup/tests/core/target/../../../test-files/Windup1x-javaee-example.war to /home/ondra/work/Migration/Windup/tests/core/target/windupreport/archives/Windup1x-javaee-example.war vs. INFO: Unzipping ../../../test-files/Windup1x-javaee-example.war to windupreport/archives/Windup1x-javaee-example.war The base path may be stated just once somewhere else. From my experience, using relative paths may get tricky, needing to carry the base path(s) along with the relative, but still, is worth the work. my2c, Ondra
