fix(readableColor): add missing export of readableColor to index

[igl]

the export of readableColor() is missing in the index.js

import { readableColor } from 'polished' does currently not work

[igl]

That precommit hook does not work as intended either:

~/polished (master +) λ git commit -m "add missing export of readableColor"
husky > npm run -s precommit (node v6.11.2)

 ✔ Running tasks for src/**/!(*.test).js
 ↓ Running tasks for src/**/*.test.js [skipped]
   → No staged files match src/**/*.test.js
husky > npm run -s postcommit (node v6.11.2)

INVALID COMMIT MSG: does not match "<type>(<scope>): <subject>" !
add missing export of readableColor

husky > post-commit hook failed (add --no-verify to bypass)
[master 78550f4] add missing export of readableColor
 1 file changed, 2 insertions(+)

~/polished (master) λ git log -1 --pretty=%B
add missing export of readableColor

@igl Thanks for catching and fixing this. By the precommit hook not working, you mean that it isn't blocking the commit despite not meeting the format?

@bhough Yes

I did --amend and force pushed with the correct title now.

@igl I will take a look at why that might be happening. Just tried on my side and it didn't create a commit, so will need to dig further. Thanks again for the fix.
