Massively improved ship editor performance on ships with many modules.
Slightly improved combat performance.
Updated player-created Chinese translation.
Removed the "Launch with System Java" launch option, as it's no longer useful or used by anyone.
Mods are no longer automatically enabled when they're installed. Instead, newly installed mods are listed in the main menu, and you're prompted to enable them in the mod manager. This is to prevent the game from choking on attempting to load dozens of mods. Especially if you installed the game on a new machine, it would try to load every single mod you ever subscribed to.
