CabalInspector and ModuleInspector are cabalized and are
automatically built using cabal-install on a sandbox. This
means that the user no longer needs to install haskell-src-exts,
aeson and haddock (on the user db) beforehand, and that
SublimeHaskell won't break every time ghc is updated.
Removes dependencies from README.md
