- all Memories can now be used to reload recorded data on startup (tested with Vision, RobotState and ObjectMemory)
	- VisionMemory seems to override the loaded snapshots, this needs more investigation

Currently all snapshots are loaded from all core segments and all days of the memory server.
The method gets called by the memory server component itself.

Moved Trajectory to aron::common

- the RobotStateMemory requires a running RobotUnit.
