b50a7318fb Add new Haskell linter (#742)
* Add stack-build linter for Haskell

The stack-build linter works better than the other two linters when
you're working with an entire Haskell project. It builds the project
entirely and reports any errors.

The other two Haskell GHC linters only work on single files, which can
result in spurious errors (for example, not being able to find imports).

* Document all available Haskell linters

* Split GHC checkers into separate files

4b0f3257dd Remove 'col' from linters where it is hardcoded to 1 (#434)
* Remove 'col' from linters where it is hardcoded to 1

When 'col' is 1, the first column will get highlighted for no reason. It
should be 0 (which is the default).

In the scalac linter there was also a check about the outcome of
`stridx`. It would set l:col to 0 if it was -1, and then it uses
`'col': l:col + 1` to convert the outcome of `stridx` to the actual
column number. This will make 'col' equals 1 when there is no match. We
can remove the check because `-1 + 1 = 0`.

* Remove outdated comments about vcol

vcol was added as a default, and the loclists that follow these comments
do not contain 'vcol' anymore

06fe8a043f Add hdevtools linter for haskell
This adds support for the hdevtools haskell linter
https://github.com/hdevtools/hdevtools

The output for hdevtools is near identical to the ghc output so this
also extracts the ghc handler into the handle file and adds tests

* Add testing for previous major release of ghc

0ffef758ae Improve formatting of ghc and hlint haskell linters
For ghc, it seemed that the conditional

```
if l:corrected_lines[-1] =~# ': error:$'
    let l:line = substitute(l:line, '\v^\s+', ' ', '')
endif
```

was never being reached. It's actually better to unconditionally
collapse whitespace anyway and so I simply removed the conditional
check.

For hlint I added more information about the error. This changes the
reported error from `Error:` to something like:
` Error: Avoid lambda. Found: \ x -> foo x Why not: foo`

Add support for dot-seperate linters, improve linter tests
This PR first and formost implements support for dot-seperate filetypes,
a very trivial change.

This closes #132

But more importantly, this PR vastly improves the test quality for
`ale#linter#Get`. It enables us to reset the state of ale's internal
linter cache, to facilitate better testing, as well as making use of
mocked linters instead of depending on linters on disk (which may
change). In addition, a dummy linter is defined to test the autoloading
behavior.

Header guards were removed from all linters as:

* A: ale won't try and load linters if they already exist in memory
* B: we can't reset state for testing if they can't be loaded again

7f0ce89d2b First pass at optimizing ale to autoload (#80)
* First pass at optimizing ale to autoload

First off, the structure/function names should be revised a bit,
but I will wait for @w0rp's input before unifying the naming style.
Second off, the docs probably need some more work, I just did some
simple find-and-replace work.

With that said, this pull brings major performance gains for ale. On my
slowest system, fully loading ale and all its code takes around 150ms.

I have moved all of ale's autoload-able code to autoload/, and in
addition, implemented lazy-loading of linters. This brings load time on
that same system down to 5ms.

The only downside of lazy loading is that `g:ale_linters` cannot be
changed at runtime; however, it also speeds up performance at runtime by
simplfying the logic greatly.

Please let me know what you think!

Closes #59

* Address Travis/Vint errors

For some reason, ale isn't running vint for me...

* Incorporate feedback, make fixes

Lazy-loading logic is much improved.

* Add header comments; remove incorrect workaround

* Remove unneeded plugin guards

* Fix lazy-loading linter logic

Set the wrong variable....

* Fix capitialization
