Subject: client: search in nodes and attributes

Fixes #358

Implementation limitations:
- uses hasOwnProperty for search, and further filters on strings. So
  technically could be oversearching - i.e. string properties that are
  not attributes. We should keep an attribute key on Node and Link
- there is no selected link, just selected nodes. So we select both
  source and destination. Opening issue #367 for this.
