add :keywords? option to wrap-json-params handler

[alexott]

This patch allows to specify :keywors? argument to wrap-json-params handler

P.S. btw, why the explicity map is used for options like:

(wrap-json-params handler {:keywords true})

instead of more standard

(wrap-json-params handler :keywords true)

?

The wrap-keyword-params already translates parameter names into keywords, so a :keywords? option is unnecessary.

As for why it uses the former syntax instead of the latter, it's because it's much easier to work with option maps when they are not expanded out. Compare:

(wrap-json-params handler options)

To:

(apply wrap-json-params handler (apply concat options))

I should also point out that the former syntax is more commonly used.

Also, this has been discussed before in #1.

And in #4 as well...
