Add backgroundColor prop

[ssomnoremac]

Pros:

• according my my own study this is the most common style used.
• would be easy to add

Cons:

• Would be the first prop on RN-row to address a style style rather than a layout style
• Could add bloat to the instance of Row/View unless perhaps we shortened the prop name
• bgColor, color, bg, background, we'd have to pick one of those rather than backgroundColor in my opinion

IMO you'd be better off keeping this library very focused on layout related concerns.

@tacomanator , I agree, thanks. I'll leave the branch just because it saves me hundreds of lines of style definitions.
