We no longer care about compatibility with so old browsers

so that when things goes wrong we can make a debug build

also run npm audit --fix to fix a security issue with webdav-fs

because we are still using it on tests machines

also update webpack

so that tools (my primary use case: ack)  understand this is minified

 * just build a library that does not create an editor
 * set a name in package json
