'v5' follows Luke & Scott recommendation.
Moved the *.avpr and *.avsc files to src/test/avro/.
The plugin config is simpler.
The only thing I've left is that the generate d java code goes to target/generated-test-sources/java (instead leaving the default target/generated-test-sources/avro directory).
The reason for this is that in Eclipse, the generated*sources/<DIR> directories have to be manually added to the IDE directory and by keeping java it is a single dir that has to be added instead multiple.
