Added .editorconfig

An attempt at preventing this (indent_style = space, indent_size = 4) and this (trim_trailing_whitespace = true) in the future 😉

What does this https://github.com/NancyFx/Nancy/pull/2035/files#diff-1e70daafb475c0ce3fef7d2728279182R11 do? Not add an extra blank line at the end of the file I hope?

Also, are all the Xml related settings compatible with the default indentation? Don't want it to affect all web/app.config etc files that we already have in our solution

Yes. That's exactly what it does. Some background:

Probably not (is there an existing standard?), but it's not as if this magically goes through all config files and changes them. This will make sure the indentation is changed correctly over time.
