v1.3.2 - Huge Stability Boost

CSSLoader v1.3.2

With this update, we have cleaned up (nearly) all of the issues raised by the recent SteamOS and decky changes, as well as retaining compatibility with both Stable and Beta branches of SteamOS. Additionally, the "Manage Themes" page now properly loads on Stable branch, instead of loading infinitely.

Hopefully this means a much smoother experience for all users.
