* Add stylish-haskell as a fixer
`stylish-haskell` is a common formatting tool for the haskell toolchain.
It is not as advanced as `brittany` or `hindent`, but it is commonly
used for formatting of imports and data declarations. This adds it as a
fixer in ALE.
* Adding support for haskell-ide-engine
* Work with the current directory if no stack.yaml file is found
* Added Cabal file detection, updated documentation and added tests
* Updated help
* Vim scripts shouldn't have hyphens
Especially not ones that will be autoloaded. You can't have a hyphen in
a function name, so autoloading functions based on filename will fail.
* Add g:haskell_stack_build_options, default: --fast
If we're going to use the --fast option, we may as well go the whole 9
yards and let the user configure the 'stack build' flags.
* Create documentation for stack-build options
