Use '[[' and ']]' instead of bare '[' and ']'

[futuro]

Evil-unimpared uses [-<SPC> and ]-<SPC> to add spaces above and below the current line, but when you add evil-cleverparens-mode to the clojure-mode hook it clobbers the whole prefix space with evil-cp-previous-opening and evil-cp-next-closing.

If the mappings were to use [[ and ]] instead then the [ and ] prefix spaces would be left open for other packages to utilize as well.

I am so used to the way things work as it is, and I use [ and ] a lot, that I won't change this for the default case. I think it should be possible to customize the keys for each user if they conflict with other packages.
