workspace shares (#84)

Feature: New 'workspaces' service which allows a user to share a local folder via zenserver. A workspace can have mulitple workspace shares and they provie an HTTP API that is compatible with the project oplog HTTP API. Workspaces and shares are preserved between runs. Workspaces feature is disabled by default - enable with --workspaces-enabled option when launching zenserver.
