Only first level transitive dependencies are left, when
transforming sample build definitions from library to project
dependencies. Therefore explicitly add akka dependencies that
samples use.
* load sample builds from their definitions and replace library dependencies with project ones
* remove redefined sample build definitions
* test osgi sample by running a maven command
* take advantage of latest incremental compiler improvements
* scala 2.10.4
* Remove workaround in FutureSpec, bug fixed in Scala 2.10.4
* Change version of samples to allow snapshot overwrite in publishM2
* allow publish overwrite for osgi-dining-hakkers/uncommons
