EpilogDriver Fix: Wrong resolutions for EpilogZing. Also split a job if the parts have different resolutions

Fix: XMLEncoder seems to irgnore inerhited getters and setters, which caused VisiCut to always loose settings on Epilog cutters

Laos: TFTP support (untested)
Added: LibInfo class with Version and Driver Information
Added: Moved JUnit tests (old and stupid) from VisiCut
Added: getDriverName() method to LaserCutter interface
Changed: EpilogCutter splittet into EpilogZing and EpilogHelix
