vifm: Fix tabular data visidata opening and preview

Tabular data was only opened in visidata if it was a csv file,
now we also correctly open xlsx, tsv, and even json files.
Also do not display an extra file title in the tabular previewer
since we already know which file we are pointing at to gain some
space.
