eclipse: add support for generated files management for java and python

added support to search and add into source path also generated source
files for both java and python. this is useful when using generated code
(ie. protoc and pyqt5) so browsing in eclipse works correclty adding also
paths where generated code is done.

extended example in playground demostrating generated code
