Start replays from the admin menu

Have an UI in the admin menu that works the same as the "select next mission".

1. Get the list of available replays by calling DynamicFrontline.get_replays (ensure you have the latest DF build for that)
2. Optionally select the number of FPS [default 30)
3. Press the button that will then call FRL_DynamicFrontline_fnc_createReplay

Bonus point for filtering the replays by available maps (the map name at the end should match the currently loaded map, otherwise, the whole replay is pointless)
