small fix
Merge branch 'master' of github.com:cordjs/core
Future improvements:
* when() method now recognizes semantics of Future.single() and not calls fork() for locked futures.
* when() method now passes arguments of the source futures done or fail to the target future
* added check for fail() method argument type to avoid confusion with using it instead of reject()
removed warning about duplicate browserInit
Models caching in the browser's localStorage!
and:
* ModelRepo::query() now returns Future.
* Collection::sync() is fully rewritten. Added notion of query queue of the collection to be more consistent in server requests.

A lot of code. Dangerous commit! Still need to refactor and comment.
