Use smart pointer to pass ownership across functions.

Use smart pointer to pass ownership across functions.

Changed methods that take ownership of an object passed as a parameter
to take a gmx_unique_ptr instead of a plain pointer.
Changed methods that pass ownership of an object out as a return value
to return a gmx_unique_ptr instead of a plain pointer.

For all module pointers using boost::shared pointer because
caller of AbstractAnalysisData::addModule() should be able to keep
ownership but should not be required to keep it.
