fixes classpath configuration
fixes XML DefaultErrorHandler warning
introduces executor service for RUL parsing

The RULs are all printed on the same thread now and the result
will be queried for success.
updates to jDBPFX 1.0.4
adds a non-strict default mode

This mode (now default) does not fail if settings file does not exist,
but allows for user input of input and output directory. This is a
better solution than failing without giving the user a chance to solve
the problem.
