#18 movie-title script update for latest version of identify

[Martin Ward]

The latest version of identify does not automatically add a newline to the end
of the formatted string it produces. I changed this line:

identify -format "%w %h" "${TITLE}/${title_frames%% *}" > "${TEMP}"

to:

identify -format "%w %h\n" "${TITLE}/${title_frames%% *}" > "${TEMP}"

and the script now works again.
