Define output path for jdt2famix

[alexlehn]

The output of the invocation of com.feenk.jdt2famix.injava.Main is generated in the current working directory. So if jdt2famix is integrated in a build of a greater project this leads to manually (or scripted) copy the ouput files '.ipr', '.iws' and '*.msi'.
It would be great if the jdt2famix has something like an output path argument like

$jdt2famix --output [PATH]
