sharedmem: config, sethostname call freesharedmemory and call setupmulti, freesharedmemoy(nonstatic) also cleans up member variables to make it consistent with shm, sharedmemory pointer set to 0 in non static free shared memory to be able to continue within application, sethostname frees memory only if detectors found in shm, add calls addmultipledetectors, replace replaces a detector in sls detector level, should also take lines in config file that has comments in between while ignoring the comments, sethostname in slsdetector also updates client, adding object in sls when creating new shm complains if shm existed and must delete again, removed remove commands
