copy-construct _data and _desc members of StorableTimeslice instead of copying the contents "by hand"
added move constructor for StorableTimeslice
reverted recent changes, they were made not realizing that StorableTimeslice(const Timeslice&) is not the copy constructor of StorableTimeslice; added "real" copy & move constructors
Merge branch 'master' into ts_constructor
forgot to copy/move members of the base class
Merge branch 'ts_constructor' of https://github.com/spadic/fles_ipc into spadic-ts_constructor
