Fixes in entries of 1994

The manifest was updated for 1994/tvr. Rebuilt .entry.json and
index.html.

Bug status changed in 1994/tvr as well. The judges noted that it has an
incorrect result in some cases but the author actually noted this as a
feature so it should not be fixed. Other fixes/updates were made in the
bugs file as well.

similar things).
