Aryeh Gregor 0c1d7143d1 Bug 984778 - Make hasFeature() and SVG requiredFeatures always return true; r=bz,longsonr
hasFeature() always returning true matches the current DOM spec.  SVG 2
has removed requiredFeatures.  Chrome has had both of these always
return true since 2014, and they seem to have had no problems.

Even requiredFeatures="" (empty string) now returns true, matching
Chrome.
