Fixes #4 by skipping any color functions that contain a var

I should be something more generic that just send a message using postcss message api, not just related to var. If a resolution fail, we should throw a warning not just throw a fatal.

Ok, so instead of just skipping var, it should attempt to parse & convert the value, and if that fails then log a warning to the postcss result and leave the declaration unmodified?

I guess :)

Exceptions are thrown by `css-color-function` when processing an invalid value.
This change catches those exceptions and turns them into postcss warnings.

Add postcss message when color function contains a var()

Custom properties cannot be resolved by `css-color-function`.
This change skips color functions that contain `var(` and adds
a message to the postcss `result.messages`
with type 'skipped-color-function-with-custom-property'.

Closing this PR in favor of #35 and #36 to address the separate needs for turning errors into postcss warnings, and the need to skip color functions with custom properties.
