Adding tup syntax highlighting
Added haskellmode plugin

Extracted from vimball.
Not sure if it completely works correctly. Only tested very quickly.
May need to tweak some settings or the like.
Added haskell folding support

Submodule.
Added align plugin

Much like Tabularize, not sure if they're redundant or not.
Not a submodule.
Stop haskellmode from changing cmdheight
