Check values of @meiversion

[claudius108]

Check what is about values like meiversion="2013" in files mei_to_html.xsl, view_score.xq, and bibl_reference_types.xml.

From MEI Guidelines, the legit values are: 3.0.0, 4.0.0, 4.0.1, 5.0, 5.0+anyStart, 5.0+basic, 5.0+CMN, 5.0+Mensural, and 5.0+Neumes.

Yes, that looks like some very old legacy code. It's probably save to modify mei_to_html.xsl and view_score.xq, with bibl_reference_types.xml I'm a little bit unsure since this is just pseudo MEI (i.e. not a valid MEI file) anyways.
