#291 — Fix icons patching and theming issues in 241

[rock3r]

This PR fixes the SVG icons patching for checkboxes and radio buttons in 241 and on standalone, by:

1. Using the SVGs from 241 in standalone, which are 10000% less wonky than the 23* ones
2. Changing the patching logic for their colours to use the new ID-based one introduced in 241
3. Fixing checkbox and radio button implementations to remove hacks and reliably work with the new logic/SVGs
4. Resolve errors in bridge by following the hard deprecation notices' instructions

EAP 3 is just out so I'm double checking everything just in case :)

One thing left to fix: checkboxes/radio buttons in classic UI themes (Darcula, High Contrast) don't get colours properly patched

[rock3r]

Verified to work on both standalone and IDE. Required fixes to the painter hints order, a buncha extra checks (e.g. only applying the new colour patching scope on New UI themes — that are, for now, hardcoded), and some other fun acrobatics. Obviously they also changed how the theme JSONs are represented in memory in 241, which broke old UI color patching.

I took the opportunity to add KDocs to a bunch of things and to test on Windows, too. I had to fix a few issues with bloody \r\n's and / vs , of course.
