Added .editorconfig file

.editorconfig file taken directly from jQuery's repository.

See jquery/api.jquery.com#877 (comment).

@kswedberg Could you please have a look? I'm wondering whether we need an entry for each of package.json and *.yml to be set to two spaces?

[gnarf]

If that's the spacing we are using for those files (and that is the spacing that npm uses for package.json) I would agree that we should add those to the .editorconfig

[agcolom]

@gnarf Thank you very much for checking. @AurelioDeRosa would you be able to add this? Thank you so much!

[kswedberg]

So, based on the OP and comments above, I think it might be a bit more "DRY" to do it like this:

[*]
end_of_line = lf
charset = utf-8
trim_trailing_whitespace = true
insert_final_newline = true
indent_style = tab

[**.json]
indent_style = space
indent_size = 2

[.*]
indent_style = space
indent_size = 2

Thoughts, @AurelioDeRosa , @scottgonzalez , @gnarf, anyone?

[AurelioDeRosa]

I think we can combine the second and third sections and use:

[*.{json,yml}]
indent_style = space
indent_size = 2

[scottgonzalez]

I would limit to package.json and *.yml. Other .json files use tabs.

[AurelioDeRosa]

Something like?

[{package.json,*.yml}]

[gnarf]

I think it's a lot clearer to just list the stuff twice for that... no reason to like not copy/pasta two lines of indent/size settings...

[package.json]
....

[*.yml]
....

feels a lot easier to understand at a glance than using the not as well known {a,b} glob syntax

[AurelioDeRosa]

Fine @gnarf. So I'd say that the final file should be:

[*]
end_of_line = lf
charset = utf-8
trim_trailing_whitespace = true
insert_final_newline = true
indent_style = tab

[package.json]
indent_style = space
indent_size = 2

[*.yml]
indent_style = space
indent_size = 2

If everyone is happy, I'll make a final PR and then merge.

[kswedberg]

LGTM! Thanks for sticking with this, @AurelioDeRosa .
