Fixed matchStates reference error in FTA display.

When I run the FTA display page during a match, I get this error in the browser's console:

`Uncaught ReferenceError: matchStates is not defined fta_display.js:24`

It breaks when it tries to look up something in the matchState dictionary, because it is defined in match_timing.js, which isn't included in the fta_display.html template.  Including that js file fixes the issue and makes the display work.
