types: `connect` should allow `null` as the first argument

[no-stack-dub-sack]

connect appears to allow a a null argument as the first argument, in the event that you only need to fire an action from a particular component, and do not need to map any state slices to your component's state. e.g.

constructor(public $ngRedux: ngRedux.INgRedux) {
  this.unsubscribe = $ngRedux.connect(null, componentActions)(this);
}

However, the types for connect are not written with an overload to support this. This forces you to write a mapStateToThis method that is ultimately not needed. It looks like there are some other changes holding up the 4.1.0 release, so this could be an easy fix to sneak in before that release.

Will you accept a PR to fix this?

@AntJanus do you happen to know who might be able to answer this for me? I'd love to make a contribution before the next release if I can (assuming this is something the team is interested in seeing).

@no-stack-dub-sack I'd accept a PR for it. It looks like the typing is a frequent issue and I don't have much knowledge about it.

@AntJanus cool , thanks - I'll work something up in the next few days, and I'll take a look through the rest of the file to see if anything else jumps out at me while I'm at it.
