Added asyncDispatch option (defaults to true). Added support for automatic store naming. Added tips doc.
Version bump.

* Refactored `factory` away.
* Changed `manager` to a class. They are persisted across `define` calls. There are no differences between a storeManager and a clerkManager anymore.
* An Error is thrown when an instance property is redefined in a builder function.
* Made `.getStore()` in a builder safe -- It will return a stubbed instance if it's not defined yet.
* Added support for (unnamed) inline stores (generates store name if undefined).
