How about release MINE check when loading files?

[14725]

Since now the browser knows more and more media formats, and the decoding in fact doesn't refer to MINEs, why not release or remove the file MINE checking?

It really brings troubles. For example my mobile refuses to load WAV until this 'if' got crossed out.

Maybe it's because my mobile uses audio/x-wav or something else, but I'm not sure.

In addition the removal of this check also allow the AudioMass to extract audio from a video, which could be a new feature.
