Support for .eslintrc alternative filenames

[silverwind]

ESLint added support for alternative configuration files names like .eslintrc.yaml. It'd be cool if this plugin could support them (I see it's hardcoded to .eslintrc right now).

@silverwind PTAL at #13. I proposed a possible solution to this problem.

I want this feature as well. My team prefer using .eslintrc.js instead of json.

I've tried #13 but it seems not working for project-wise eslint config. So I took latest SublimeLinter-contrib-eslint plugin approach and it seems working as expected. Here's how I modified linter.py:

cmd = ('eslint_d', '--format', 'compact', '--stdin', '--stdin-filename', '@')

# Remove config_file
# config_file = ('--config', get_config_file(), '~')

My guess is that this will let eslint_d look for the config file by itself and it will look for one of the known config file names from current folder outwards.
