Title: Allow passing command line args to ghci

Manually overriding the haskell-process-path-ghci variable now allows
entries (among other things) like:

"/usr/bin/ghci -package-conf .cabal-sandbox/ghc-7.4.2-packages.conf.d"

This, for example, is a for-now work-around for cabal sandbox ghci support.
