Bug 657791 - Update WebM demuxer to consider cue-less WebMs seekable. r=jya It appears that the work to seek in WebMs that do not have cues has already been done, however this functionality was gated by the IsSeekable() function still returning that such WebMs were not seekable. This updates that function so that WebMs without cues are now considered seekable. Tests are also updated to reflect this.
