Ellipsize song info when too long 

When artist, title, album artist, or album are truncated, trim trailing whitespace & replace last 3 characters with "..." as long as they are longer than (char limit - 3).
Currently, "max_length" being set will cause the entire "format" string to be truncated & ellipsized, but there is no way to ellipsize the individual tags.

e.g. with artist-len == 13 and artist == "Queens of the Stone Age"
Old behavior: artist = "Queens of the"
New behavior: artist = "Queens of..."
