(MPC-BE 2296, 2297, 2309, 2342)
Revert "Shaders: shaders moved from ini and registry to separate folder."

This reverts commit 0e2e3b94584d32dd76a654869cd849757f305cc8.
"After Playback": Always give "Once" events a higher priority than "Always" events.

This commit fixes #3001.
Cache access to mpc-hc.ini (both read and write)
Make access to cached mpc-hc.ini thread-safe

Access to mpc-hc.ini cache map is now serialized.
A race was possible between filter graph thread and main thread, as
some internal filters use CWinApp::GetProfileX() functions to load its
settings.
Save mpc-hc.ini in UTF-8
Subtitles: Improve error checking with ASS rendering.

Some crashes could occur when the SSA script was using obviously wrong values.

Uses the same check as libass for maximum glyph size.
