v0.9.4

• #251 - Fix typo in Doc.js: lenth -> length (@distracteddev)
  • This fixes a logging issue with debugMutations on, where a locally-issued mutation on a remote collection would only get logged with its collection+id, when it should have also included the subpath under the doc.
• #259 - Dedupe queries when calling model.unbundle (@ericyhwang)
  • This allows model.unbundle to be called multiple times, with fetch/subscribe counting incrementing appropriately each time.
• #260 - Add Model#_getOrCreateQuery method (@ericyhwang)
  • Mostly an internally-facing change, which allows Query subclasses to be created without code duplication.
