Added repo settings

.editorconfig copied from Roslyn, except prefixes "s_" and "_" for
static and instance fields respectively, and the suggestion to not
prefer expression bodied members for ctor, method and operators.

See https://raw.githubusercontent.com/dotnet/roslyn/master/.editorconfig
for reference.
