0.10.226 - Inverse Camber

This is the first new-track update that doesn't contain a video of me running it, because now there are leaderboard ghosts you can watch.

• added a new Stage 1 track, Inverse Camber

• fixed some bugs related to leaderboard ghosts

• re-recorded some personal ghosts that were old and/or corrupted

• added the "Locally Hated" achievement and corresponding wheels

• added the "Jinba Ittai" achievement and corresponding wheels

• only upload ghosts if necessary, not each race start/each finish

• properly handle some file I/O asynchronously to remove lag spikes at race end

• stop playing ghosts when respawning

• fixed a display bug with locked cosmetics

• embed currently applied wheels in Ghost recordings
