Changed to snapshot version; added maven repository for deployment
Added automatic deployment to sonatype repo with travis
Fixed classloader delegation of task conf
Added maven-profiles to enable switching between yarn and non-yarn hadoop
Remove pact-examples dependency in pact-clients.

pact-clients was dependent on pact-examples in order to run
LocalExecuterTest. The problem with that was, that this prevented the
use of the LocalExecuter within the pact-examples module (circular
dependency). Hence the LocalExecuterTest was moved to the pact-test
module and the pact-examples depedency was removed from pact-clients.
First part of fix to exclude pact-hbase when hadoop v1 is used
Added extra profile entries in the pom.xml files in order to fix the hadoop_v1 compilation problems.
Merge pull request #1 from aalexandrov/hadoop-maven-profiles

Fix from Alexander, so that pact-hbase is only included if yarn is used (because it is not compatible with hadoop v1)
Made the hadoop_v1 profile active by default.
Moved hadoop.version property to the profiles.

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.
