Add initial support for smartparens-mode.

[hrathod]

I have added some functionality to make smartparens-mode play nicely with clojure-mode by making the literal set notation and lambda shorthand notation easier to work with.

This was merged before I could comment, but isn't setup like this one usually bundled with smartparens itself?

Yes. It doesn't belong here.

[Fuco1]

We don't have setup for clojure yet though. @expez would you like to port this over?

[Malabarba]

Sorry. Since we had something similar for paredit, I thought it was straightforward to do the same for smartparens.

[bbatsov]

The only reason we have the paredit code is that it's pretty hard to push any changes to paredit itself. I'm not opposed to having the smartparens code in clojure-mode, but I do believe it's best to follow the common sp conventions and the bundle the necessary config with it.

[Malabarba]

👍 I agree.

[hrathod]

Shall I create a new PR to revert these changes, then? Or has that already been done?

[Malabarba]

I can revert the changes here. I was just waiting for someone to open a PR on https://github.com/Fuco1/smartparens

Since it is apparently agreed upon that this code should go in smartparens, and since this is causing other issues (#386) I decided not to wait.

[hrathod]

Sorry for the troubles!

[Malabarba]

Not at all! Thanks for the effort. :-)
The troubles were my fault.

In the meantime @vspinu has started (probably independently) an effort to add some settings: Fuco1/smartparens#593

Anyone want to jump in?
