Carlsen TMER: Adding the Venues

Continuing with TMERs : One Step at a Time, I added venues to the index page for Magnus Carlsen's Tournament, Match, and Exhibition Record (TMER, 2000-). This was done by extracting the data from the 'Site' tags in the PGN file for each event (as described in Carlsen TMER: Splitting the PGN File and Linking the Record and the Games), then adding it to each event in the TMER. Afterwards I removed the venue from any event where it was duplicated. About half of the events already had a venue listed.
