Rename SetId() to setId()
Hopefully fixed a bug in the pact compiler for branching plans:
	- added a test case provided by Anja Kunkel from HU Berlin
	- my understanding of the bug is the following: During a check if additional pipeline breakers are necessary,
	the compiler checks for the LocalStrategy of a SinkJoinerPlan. The SinkJoinerPlan is a "fake" plan element to group multiple output sinks into one sink (the compiler assumes one root node, this is why a "fake" plan node is required).
	The local strategy of SinkJoinerPlan is initialized as NONE, which means that we just pass through the elements (which makes sence since we are talking about a sink) The initialization of a NONE-local strategy assumes only one input, not two.
	I replaced the LocalStrategy with BINARY_NO_OP, which is a NONE for two input.
	The compiler is now able to do its pipline breaker checks.
Fixed nephele-config.sh substr command calls on OS X (closes #88)

Fixed nephele-config.sh substr command calls on OS X (closes #88)
Added ALL_GROUP strategy to PlanJSONDumpGenerator. Before this fix the pact web could not show the plan.
Merge pull request #105 from andrehacker/fix_web_all_group

Added ALL_GROUP strategy to PlanJSONDumpGenerator.
1) Changed profile activation to properties (like hbase) 2) moved all properties to top of pom 3) moved module list to top of pom
Remove unused exclude-statements in assembly-descriptor (exclude elements can only define artifacts, not paths)
Added hbase inspired script to generate poms for hadoop1 and hadoop2 (yarn)
Added relative path to all poms
Travis support for new profiles, readme, comments in script
Removed TeraSort from example jars when packaging
Merge pull request #102 from uce/remove_terasort_from_build

Remove TeraSort from examples
Merge pull request #111 from rmetzger/gith_andre_new_profiles

Support for different Hadoop versions (yarn!) using activation by properties
Mailing list link in README
Improved readme

With help from @uce
