This reverts commitd29f851e82. Making <img>s responsive by-default without opt-in can severely break third-party widgets such as Google Maps. This was an acknowledged problem in Bootstrap v2 (see https://github.com/twbs/bootstrap/issues/1506 ) and was fixed in v3 by requiring the .img-responsive class for explicit opt-in (see09cdee2f03). The situation hasn't really changed since then. The responsive-by-default approach hasn't become any more suitable in the intervening time. So let's avoid having this regress in v4. :-)
