Support for the Haskell programming language in visual studio code.

Adds highlighting support for Haskell (.hs and .lhs). This is a (now heavily) modified version of the syntax file from the Haskell TextMate bundle. Additionally there is support for and Cabal files (.cabal) via a concoction of my own.

Also adds automatic indentation after where, do, -> etc. and surrounding brackets ([], {} etc)



Includes common Haskell code snippets, such as data and newtype declarations, main module, if and case.

If you happen to notice bugs or have suggestions for improvements visit the issue section of the repository.

Thanks to @Miguel-Fontes for enabling support for literate Haskell.
