Use original shnippet in place of haskell-yas.

[gracjan]

Fixes #361.

Original 'shippet' is well maintained at https://github.com/LukeHoersten/shnippet. Someday it should be added as a git submodule. For now users are advised to refer to the original version directly.

Note that haskell-yas was a simple rename of shnippet and does not offer any additional functionality.

Have changes been made to the snippets following the import and renaming? shnippet hasn't been touched for a year.

I like the idea of keeping this out of haskell-mode, but until shnippet can be installed via package.el, I'd be wary of removing haskell-yas from the tree.

It's not completely unheard of for major modes to bundle yasnippets, even without declaring a package dependency on yasnippet, though, so if the other maintainers would prefer to keep this here then I don't feel strongly either way.

[gracjan]

Imported snippets have not been changed since import. There also have been zero issue reports about snippets. Both strongly suggest that users do not care about shnippets inside haskell-mode.

Packaging shnippet properly is a very good idea that should be brought up in original repo: https://github.com/LukeHoersten/shnippet.

[gracjan]

As per #305 haskell-mode snippets are activelly maintained here: https://github.com/AndreaCrotti/yasnippet-snippets, haskell snippets are in subdirectory:

https://github.com/AndreaCrotti/yasnippet-snippets/tree/master/haskell-mode

Last change was done 20 days ago there, that indicates active comunity involvement.

That looks like a user fork with personal snippets. Not sure if it's usable. Best option is still to either keep the status quo, or package shnippet then merge this PR.

I still actively maintain shnippet - I'm not sure about AndreaCrotti fork since I've received no PRs. We should still come up with a better way to package shnippets into haskell-mode. I like the subrepo idea.

Oops ment to open the issue not the PR.
