Virtual Contact generation errors

[alecive]

When running virtualContactGenerator module, I get the following:

 virtualContactGeneration --skin_parts::SKIN_LEFT_FOREARM on --robot icubSim
...
[INFO]Module name set to virtualContactGeneration
[INFO]Robot is: icubSim

Two issues are there:

1. The yError that is printed out should be solved
2. The thread should exit before encountering the exception. By simply returning false after https://github.com/alecive/periPersonalSpace/blob/master/modules/virtualContactGeneration/virtContactGenThread.cpp#L131 should be sufficient. Maybe it would be useful to handle also the return false on initSkinParts(), i.e. close the module at #L126

good point! Solved second part - proper closing. Will work on first part - the forearms were really simply not implemented.

Should be solved now, you can test.
