Passing theme explicitly in props

Feature request

Similar to https://github.com/styled-components/styled-components/issues/294, I would like to be able to pass a theme directly to a styledComponent (overriding the one supplied by ThemeProvider if existent). Back then, this was fixed in https://github.com/styled-components/styled-components/commit/14c1c29deb7244129621a0333b2dc06b669f2f0d, but I suppose, this change was reverted by refactorings.

I imagine sth like:

       {/* All children of this component will be red */}
        <ThemeProvider theme={redTheme}>
            <div>
                <Button>I'm red!</Button>
                <Button theme={yellowTheme}>I'm yellow!</Button>
            </div>
        </ThemeProvider>

This makes it easier to override the theme for single components and better testing. Are there any caveats for having this?

Thanks
