Also fix an annoying bug that made tests fail because a dependency on
scala-reflect was wrongly in the "test" scope.

Also make alle the examples that work implement PlanAssembler and output
generated example jars for these examples to examples/pact-scala in the
distribution.

[ci skip]

Changed branch handling logic to correctly recognize disjoint data flow graphs, rather then erroring out.

End the version name craziness and go back to have 0.4-SNAPSHOT as
version number. Also change the name of the toplevel pom back to
stratosphere.

[ci skip]

Add filter on Join and Cross in scala frontend

Added test case for catching simple disjoint cases.
Added test case for a more complex case of a branching but disjoint data flow graph (deactivated now, as it is not yet caught by the compiler).

Pom-generate script now allows to specifiy a filename for the pom
new script to rename poms

- Unified config to stratosphere-conf.yaml, which replaces the old
  nephele-user.xml and pact-user.xml and is also read by
  bin/nephele-config.sh

- Removed some settings from config:
    * instance configuration
    * multicast for broadcast
    * profiler impl classes
    * jobclient.polling.interval (adjusted default from 5 to 2)
    * pact.runtime.fs_timeout

Use the new cooridnates for it.
Fix a warning in pact-hbase/pom.xml.

Fixup scala examples

Some examples do not work due to bugs in the runtime (iterations). For
those tests that don't work we don't yet have an integration test so
that mvn verify will not fail.

Added getUserCodeClass to UserCodeWrapper

Scala examples for Triangle Enumeration

Serializer fixes

Iterator of analysed list types was not correctly generated when arrays
are used.

* new link to mailing list
* fixed #149
* Added dima irc channel

(HDFS doesn't like invalid ranges and returns an empty array in this case)

Fix bug with user-code wrappers

The problem was that the user code wrapper was not deserialized from the
config using the user-code class loader. Now we jave a custom
ObjectInputStream that uses the user-code class loader to resolve
classes.
