one more MSG example to go to the dungeon
Fix memory leaks.
Make room for the upcoming network energy plugin
New function: MSG_parallel_task_execute_with_timeout This is the fist time that executions can finish with a timeout, and I'm not really proud of the resulting code. Sorry, that's just a quick (fix #115) while I was fixing the platform generation. At some point the whole activity thingy should be reworked, too.
Test that ptasks with 0 exec and 0 comm do work

reorganize examples/msg/energy Note the parallel_task_energy tests included the parallel_task test, then keep the energy one only and rename it.
