Not deleting duplicate color declarations.

[lumberman]

Hello, I believe the library has hard time to delete duplicate color declarations if rgba used.

For example if you try this code: .foo { color: #ff0000; color: rgba(13,13,13,.03); }

CSSO will not remove duplicate colour declarations.

@lahmatiy any chance to take a look at this issue? Thank you!

actually, it keeps them on purpose, to avoid breaking the fallback for browsers not supporting rgba

CSSO doesn't merge declarations in this case because of

to avoid breaking the fallback for browsers not supporting rgba

On the one hand, browsers that doesn't support for rgba() is not an issue anymore. On the other hand, that's not a single issue (e.g. values with rem, vw and vh units or selectors with :hover, ::before/::after pseudos are also an issue) and somebody may need to keep fallbacks for old browsers. I planned to add an option to specify which fallbacks is needed to respect. Unfortunately, this feature may take much more time that I have currently.
