Release core-1.4.2.2 to support mtl-2.3

Release core-1.4.2.2 to support mtl-2.3.
I get to work.

[andreasabel]

I tested mtl-2.3 compatibility by cabal build core with the following cabal.project.local:

constraints: mtl == 2.3
allow-newer: mtl

-- random
------------------------------------------------------------------------

source-repository-package
  type: git
  location: https://github.com/haskell/random.git
  tag: 5ecc8935994159c6d39088233a0887714aacaf5e

constraints: random == 1.3.*
allow-newer: *:random

The testsuites are still blocked by at least:

• Support transformers-0.6 and mtl-2.3 byorgey/MonadRandom#50
• Support mtl-2.3 Bodigrim/logict#31

[andreasabel]

I realized I have no upload rights on hackage. So I have to unassign myself.
The release preps are in this PR:

• Bump core to 1.4.2.2; CHANGELOG #334

@andreasabel Any chance we could cut a Hackage release? The lack of such blocks me from giving you the tests you requested.

[andreasabel]

@UnkindPartition : Would you mind adding me to the hackage maintainers of tasty?

[kozross]

@ocharles - As per @UnkindPartition's code will, would you be able to help out @andreasabel and myself?

[andreasabel]

I emailed Oliver Charles about it.

[andreasabel]

@kozross: I you want to get started with using tasty as testsuite for mtl, you can use the no-mtl branch (#335) per source-repository entry in your cabal.project.

[ocharles]

@andreasabel @kozross @UnkindPartition all done!

[andreasabel]

Released tasty-1.4.2.2 to hackage.
