stack dot --[no-]include-boot-libraries

[sjakobi]

stack dot already has a --[no-]include-base flag to hide dependencies on base which about every package has.

The boot libraries are similar to base in that they are included in every GHC installation. Excluding all of these could simplify many package graphs.

An alternative suggestion for the name would be --prune-boot-libraries.

For now I'm using the following option:

--prune "Cabal,array,base,binary,bytestring,containers,deepseq,directory,exceptions,filepath,ghc-prim,haskeline,hpc,integer-gmp,libiserv,mtl,parsec,pretty,process,rts,stm,template-haskell,terminfo,text,time,transformers,unix,xhtml"
