New features

Several bug fixes. They are applied to tdaq-01-02-00 as well.

The function did not kill all test executables in case of several tests per component.
The session did not have LD_LIBRARY_PATH correctly defined. It is fixed.
The VME_INTERFACE case was not working. Attempt to get from database a class VME-INTERFACE which does nto exist, class name is  "Module" in this case.
Function did not work properly. As well in Applications Log Browser the information was not updated when the database was reloaded. It is fixed.
Incorrect loading of classes derived from "Crate", Module", "Detector". Classes derived from base classes were not loaded by the dvs manager, so setup_daq was not working. Search for superclassesof these extensions solved the problem.
