  • dumped threadtweak, it's abandoned and it's likely to've been reducing performance atp
  • reduced c2me's worker thread priority to 3 from the default 4

Added a third-party port of ModernFix.

This version is very complete but i cannot in good conscience mark it as a release since it spams errors on load.

Seems to work fine, but keep an eye out for breakage and report anything critical to me so i can react.
