another connector approach started
attempting to fix implementations for connect/tryConnect etc
api improved, some methods for adding connectors have been defined (connect methods still missing)

- seems like most connector methods are correctly specified

TODO: provide an implementation inf VNodeImpl and io classes
connector based approach works:

- valueobject for connectors introduced
- io supports connectors

TODO
- valueobject interfaces have to be changed
- how about valueobjects and serialization?
verified that io works! (good vObj solution still not found)
added test dependencies (junit)
added test case for creating flow, adding nodes, connecting nodes
connector api improved: getIn puts(), getOutputs() added, connectors list can be modified (connector id stuff is updated automatically)
minor changes in test framework (we have problems with jdk8)
iotests added
error found in load: fromPersistentConnector(..) was called with wrong argument (parent instead of node)
Merge branch 'connectors' of github.com:miho/VWorkflows into connectors
api for new connectors seems to work (tests work as well)
