Support relative paths for map-includes in morph-files

[dr0i]

Using metafacture-ide, it is not possible to use relative paths for map-includes in morph-files:
" "
The root directory is not a classpath directory, but the eclipse directory.

• Full paths are working of course, but are not independent of the environment.
• Starting the transformation not using flux, but instantiating a metamorph-class directly from a java class, relative paths are working, because the classpath is granted.

May be an issue of culturegraph/metafacture-core .
