Added a NOTICE command to provide a way for clients to get messages into the clockwork message log
add a debug notice to help detect potential issue with list entries that have machine references but have not cached the machine pointer.
permit a second dereference of a symbolic value in this statement to make it possible to add a machine to a list from a property value initialised from another list. This may become a standard feature for all statements..TBD
The persistent store data structure was not adequate to support the method clockwork needs to use to load persistent properties. Entries in the store are now a map of property_name,value pairs
When adding parameters to a list, fix a bug that prevented caching the machine instance pointer in the value
update persistd to cater for the new persistd data structure
disable linger on the connection to the server from iosh
