Enables script access to the per object dynamic attributes through the JsonStore

Browse Source 
script functions. Adds JsonAttachObjectStore to associate a store identifier with
an object (scripts can only access the store in their host object, this could be
extended but isn't necessary for now).

Note this opens a method to the DAMap OSDMap. This will be removed later, but
greatly simplifies the code for now.

The JsonStore and these scripts are disabled by default.
