stats.lua: display file tags

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.
