Camel refactoring

it was really hard to understnd how camel integration works. There are also  some never reaching codes.
Now it is clearer.
De default way of copying information from activiti to camel is set by this ways sorted by priority:
   . by properties in "from" part of route. like from("activiti:asyncCamelProcess:serviceTaskAsync1?copyVariablesToProperties=true")

  . by selected behavior

The latter is not regarder if the former exists.
