This adds file tags to display along with the title, including
album/artist etc. for music, and series etc. for some videos.
The list of tags to display is identical to the tags printed to
the terminal and is controlled by the --display-tags option.
To filter out overlength tags (such as long comments and lyrics) and
files with too many tags, add file_tag_max_length and file_tag_max_count
options so that tags longer than this length are not displayed, and only
the first few tags are displayed.
Also makes tags show on page 5 only.
