0aa0dac642 Turning on -fwarn-{implicit-prelude,missing-import-lists} 
There is a small potential for a breaking change, since Data.OpenUnion
no longer re-exports Functor class. Anyway, what was that about?

3652b210e7 Renamed modules Data.Open.Union.* to Data.OpenUnion.* 
Each hierarchical part of module name should be significant, in its own
right. In case of Data.Open.Union the Open part doesn't make much sense
on its own.

7c1c7437e9 Relaxed type signature of asks function 
It's previous type signature:

  asks :: (e -> a) -> Eff '[Reader e] a

Was very restrictive, therefore, its usage was limited to very few
effect stacks. New type signature:

  asks :: Member (Reader e) effs => (e -> a) -> Eff effs a

Is much more liberal, and allows us to use `asks` in all the places we
would have to use something like `f <$> ask`.

c5d13db140 Using NoImplicitPrelude in State module 
This should help us resolve issues with various versions of base
packages more easily.

Reason for doing it now is that base bundled with GHC 7.8.4 doesn't
export (<$>) in Prelude.

84022b9103 Match coding style of runNat with the rest of the codebase 
This is really minor but the next commit adds a `runNatS` function that
would require a 5-var forall and that's starting to be really confusing,
making people think why it's there.

8060429c52 Fix "Could not deduce: effs ~ (r : rs)" errors 
Commit 4260466929 added the "r has at
least two elements" constraint to the `Member' t r ('S n)` instance but
`Member t effs` with a general (unknown) effs isn't enough to deduce
that effs is non-empty, so this doesn't typecheck:

    f :: Eff (IO ': effs) () -> Eff effs ()
    f = undefined

    g :: (Member Maybe effs) => Eff effs ()
    g = undefined

    h :: (Member Maybe effs) => Eff effs ()
    h = f g

GHC complains that it could not deduce: `effs ~ (r : rs)` arising from
the use of `g`. It can be worked around by using this instead:

    h :: (Member Maybe (e ': es)) => Eff (e ': es) ()
    h = f g

but I don't think this is a good user experience, and it's a regression
from 0.2.3.0 that would normally require a major version bump to 0.3 as
it breaks existing code. Therefore a fix should go in quickly and should
get into lts-7 asap.

This commit adds the "effs is non-empty" constraint to `Member t effs`
so the above typechecks again.
