Allow loading of LTM exports to the Viewer, although the memory servers have not been started
Steps if you want to test:
- Make some memory export and store it somewhere on the FS
- Kill all memories. Only start armem core scenario
- Open memory viewer GUI, disable drop of disconnected memories
- load the export
If a memory server is running -> the imported data will be commited to the server (as before) If no memory server is running -> create a new virtual memory (only available in GUI) and show data there
