added typings for dynamic array of uniform selectors

[sergey-su]

Currently array version of createSelector typing has fixed number of selectors known at compile-time. However createSelector's implementation supports any number of selectors determined at run-time. Technically input selectors can have different return types. That's impossible to describe in TypeScript. But it's possible to describe the case when all selectors have same return type. For example when input selectors are generated for each element of a container that has nr of elements fixed during selector's lifetime:

createSelector(containerWithFixedNrOfElements.map(obj => () => obj.value), (...values) => expensiveCalculation(values))

Can anyone re-trigger the travis build? The first one failed with an issue not related to this change.

What else this PR is missing to proceed?

Hey @sergey-su, sorry to be so late to this. I just merged another long-outstanding typings pr and seem to have introduced some merge conflicts with this pr. If you resolve them and we can find someone to review (I don't use typescript), then I'll get this merged too.

@ellbee , PR branch rebased

[jsprds]

@ellbee @DmShpak is it possible to merge this PR? Thanks!

[ellbee]

I was hoping for someone who uses Typescript to approve it, but I see @aikoven approved it before the rebase so I'll merge.

[jsprds]

@ellbee Thanks! When are you planning a release that includes this fix?

#351

[ellbee]

I'll likely release a beta sometime over the weekend. There is another TypeScript related issue that I'd like to see if we can clear up (#340) as part of v4 as I don't feel comfortable making TypeScript changes in minor versions. I don't use TypeScript personally so any help would be much appreciated!
