Allow keywords in style maps

[pesterhazy]

Reagent allows keywords as CSS attribute values such as

{:style {:color :red}}

Hiccup already supports this for top-level DOM node attributes. This commit
extends this feature to style maps.

I should mention the current behavior is to generate style="color::red"

@pesterhazy To match Reagent's convention, should integers be rendered as pixels by default?

For example:

(str (html [:div {:style {:margin 10}}]))

To:

<div style="margin:10px;"></div>

Note 1: this might be due to React's rendering engine and not Reagent's:
https://reactjs.org/docs/dom-elements.html#style

Note 2: unitless values for incorrect attributes (such as margin) are often recognised as pixels anyway by browsers.

Note 3: some attributes do expect unitless values (such as line-height).

[pesterhazy]

Yes, I think so

@weavejester Is there a reason not to merge this? This would be very helpful for me with Oz.

[weavejester]

This PR seems to have fallen through the cracks. It should be fine to merge, but the commit message body should be removed, as I think the subject is sufficient explanation.

Thanks @weavejester! Do you need @pesterhazy to edit the commit history before it gets merged then?

[shhivam]

Hey @weavejester! Could I take this? I would like to take this to the finish line.

Edit: if I can take this up, I will make a new PR and add @pesterhazy as co-author

[weavejester]

Sure.
