Initial Release

This is the initial binary release for Cayley, having now become go get friendly. Current feature list from the README is:

• Written in Go
• RESTful API
  • or a REPL if you prefer
• Built-in query editor and visualizer
• Multiple query languages:
  • Javascript, with a Gremlin-inspired* graph object.
  • (simplified) MQL, for Freebase fans
• Plays well with multiple backend stores:
  • LevelDB for single-machine storage
  • MongoDB
  • In-memory, ephemeral
• Modular design; easy to extend with new languages and backends
• Decent test coverage
• Speed, where possible.

No changes, because initial release.
