Add `python -m editorconfig_checker` support

[gitpushdashf]

It'd be nice if this had a __main__ callable, so could be invoked like python -m editorconfig_checker that would run ec or ec.exe and pass on all of the arguments.

This would allow for more portable Makefiles across Linux and Windows, and maybe solve some $PATH/rehash issues people might encounter.

Very cool project. Glad I found this.

Hi @gitpushdashf. Yes, I can try to do it as well. Let's see if I have time to work on it in the next days.

Thank you, but most of the work was done by @mstruebing. This is just a simple wrapper around the core he wrote in Go :)
