Preventin error when Binding without observer gets unbound
Fix typo
Merge pull request #359 from FND/patch-3

Fix typo in README
s/adapters.coffee/adapter.coffee.
Integrate sightglass as a single dependency. Use a predefined public object so that root keys on the module can be changed safely. Remove the config object and set all options + extensions on the module directly.
Remove the Rivets.Observer class (replaced with sightglass lib).
Update specs.
Update gulp build task to include a bundled version (Rivets + Sightglass).
Use the bundled source in the spec runner.
Don't set the root interface on the sightglass global module (we don't want to be setting this from within Rivets).
Merge branch 'sightglass-integration'
Build 0.7.0-rc1.
