Title class fetchData() added wikipedia info

[duck7000]

I added Wikipedia info for the specific title, so only for this title, not for artist or others.
All anchor tags are removed (the link text is of course not stripped out) as are the supplement anchors, those are removed completely.

It includes all the text sections like background, release, critics, etc. Every paragraph of a section is in a separate array element in a categorized array like this:
