build with rollup + babel, namespace, modal style

[mila76]

editorconfig + prettier for consistency
namespace default option
default/type style for modal

Sorry but the diff is so huge because different writing style and prettier do prettier stuff
the actual code difference is very small

N.B. sorry not tested in node
