Allow additional ESLint config file names.

[goloroden]

According to ESLint documentation, a config file may have an extension. Hence I replaced the hard-coded comparison by a regular expression that matches all possible file names.

I have seen that two of the three build steps failed, but IMHO this is fine, because:

• codecov/project is yellow for the other PRs, too. Apparently there is something not working.
• TravisCI successfully ran the tests, but failed when trying to talk to a coverage url. So the part that is really important passed.
• AppVeyor is green :-)

@goloroden Thanks very much for contributing this project. The code looks good to me. Just one more point, could you please modify test code to cover the support? I suppose to add a for-loop in around this line.

BTW, I will handle this test-coverage is failing. Don't worry about that. 😺

[goloroden]

Thanks for your fast response :-)

I have added to the tests what was needed to test the possible options.
Looking forward to the merge :-)

[lijunle]

Merged! Thank you for helping this!

@goloroden Do you want a new version on this?

[goloroden]

Basically I'd say yes, but maybe let's wait until the next PR regarding issue #174 is also merged (I need both of them for a project I'm currently working on). Is that okay for you?

[lijunle]

Sure! 👍
