Removed SPECS.md file
Added some custom domino events

Any domino instance will now dispatch events prefixed by "domino:" when some actions are happening, such as orders execution or logs.
Started adding tests about domino's async workflow

The last test that checks that domino throws an error when a property is updated in the same frame with two different values fails, since I do not know yet how to catch an error in an upcoming frame that I don't control.
Added TODO.md
Added some more stuff to do in TODO.md
Moved orders checking into the _addOrder function

From now, when a bad order is added, it will throw directly an error instead of waiting for the orders stack to be unstacked in the _execute function.
This makes possible to catch this error, so I fixed the last added unit test in workflow.test.js.
Reactivated some jslint rules
Fixed events deduplication

Also added related unit tests.
