refactor noun phrase to english

[JoeZZG]

From Refactors wiki under drasil-lang:

move Language.Drasil.NounPhrase to Language.Drasil.NaturalLanguage.English.NounPhrase

NounPhrase modules are moved to a new path in drasil-lang

Files moved via git mv:

git mv .../NounPhrase.hs             -> .../NaturalLanguage/English/NounPhrase.hs
git mv .../NounPhrase/Core.hs        -> .../NaturalLanguage/English/NounPhrase/Core.hs
git mv .../NounPhrase/Combinators.hs -> .../NaturalLanguage/English/NounPhrase/Combinators.hs
git mv .../NounPhrase/README.md      -> .../NaturalLanguage/English/NounPhrase/README.md

[JacquesCarette]

@JoeZZG you should summarize what we said at the meeting here.

[JoeZZG]

At the meeting, the suggested two comments are:

First commit: only move files with git mv (no real content changes)
Second commit: make the actual edits

[JacquesCarette]

So I guess this is not actually ready for review?
