Feature request: Numeric sort

When sorting numeric titles, Plex appears to sort by ASCII rather than doing a true numeric sort.  This called attention to itself when I set sort names for Star Trek movies to Star Trek 1 through Star Trek 12. What I got was 11 and 12 positioned between 1 and 2.  To get it to appear correct I had to relabel all the single digit numbers to 01, 02, 03, etc.  It also happens that something like "2001 Space Odyssey" sorts before "28 Days Later".

 

For the more common problem like Star Trek, simply put in a sort title of Star Trek YYYY where YYYY is the year.  This will list them in the same order as before but handles things like multiple series in an appropriate way.
