The Jython ScriptRunner is contained in the SikuliX-Jython-API project.

Conflicts:

	pom.xml -> small update
	src/main/java/org/sikuli/script/Region.java -> tabs replaced with whitespaces and fixed indent
	src/main/java/org/sikuli/script/SikuliScriptRunner.java -> deleted, is now implemented in SikuliX-Jython-API
Merge branch 'outsourcedJython'
