requesting specific Cabal version

[Bulat Ziganshin]

Hello Haskell,

what about adding to .cabal file ability to ask for specific Cabal
version? it will allow to make incompatible changes between Cabal
versions. program that uses services specific to Cabal 1.4.x, for
example, will just ask for using this Cabal version and operation will
go fine

of course, it will require to have cabal 1.4.x, 1.6.x and other
versions simultaneously installed - just like now it's possible (in
ghc) to have different versions of any other lib installed together
