ExportName for LTM exports can be set by adjusting property config file and ArmarX.MemoryName.mem.ltm.exportName property

Also stopped cloning aron data before extraction because that was only necessary for multiple LTMs

Merge branch 'feature/forgetting-in-wm-and-em' of https://git.h2t.iar.kit.edu/sw/armarx/robot-api into feature/forgetting-in-wm-and-em

- decoupled MemoryViewer in GUI from store-Thread of MemoryToIceAdapter
- added status thread to update LogViewer if files are still written and notify it when writing is finished
- removed deep_copy setting of entity instance (not needed if only one LTM is recorded)
- added property definitions for store frequency (BufferedBase) and memoryName (DiskStorageMixin, not fully working yet)

removed old comments, added try-catch for setting export name, added ARMARX_INFO output for export name information
