Features

Resetting backend fully unloads all css
CSS Loader now can create it's own api server, compatible with decky's api
- Activate this feature by creating a file called SERVER in the themes folder (or running standalone)
Standalone backend!
- Standalone backend is currently only built for windows as linux can run decky
Tab operations are now done in parralel for massive speedup during the injection routine
CEF flag for steam is created on boot if it's hosting the web api
Add flag to not install dependencies when installing themes (who uses this)
Dependencies can now be flagged as optional, showing a UI message to ask the user if they want to enable dependencies
Add stop command
Multiple images from the store are now displayed

Fixes

Log redirection by importing decky plugin
Css variables in theme.json are no longer seen as a tab instance
When multiple different regex result in the same tab target, the backend will merge these 2 tabs then reload. This fixes continous reinjection
Frontend no longer displays themes with a too high manifest version. This was a regression from v1.4.0
Environment variables now have defaults
