workspace share security (#192)

- Improvement: Reworked workspace shares to be more secure. Workspaces and workspace shares can only be created using the `zen workspace` command, the http endpoint is disabled unless zenserver is started with the `--workspaces-allow-changes` option enabled.
  - Each workspace are now configured via a `zenworkspaceconfig.json` file in the root of each workspace
  - A workspace can allow shares to be created via the http interface if the workspace is created with the `--allow-share-create-from-http` option enabled
  - A new http endpoint at `/ws` - issuing a `Get` operation will get you a list of workspaces
  - A new http endpoint at `/ws/refresh` - issuing a `Get` will make zenserver scan for edits in workspaces and workspace shares
