Optimizations! (v1.17)

In preparation for the upcoming console ports, we've introduced a few optimizations. Primarily [list] [*] Removed an issue that would cause frame rate drops on older hardware [*] Automatic system language detection and switch (if supported) [*] Better stage loading. Should hiccup less in older hardware [*] Optimizations to Sky Fire [*] Other minor fixes and improvements (mostly for consoles) [/list]
