No point using BMP, since they're way bigger, and they're not
required for authenticity, since the original files were .cur and
.ico files. At some point, I'd like to support those formats, so this
branch can use the original files.
Visual Studio 2017 doesn't like them being 0 and 1: the compiled EXE
uses the small icon as the taskbar icon. Changing them to 101 and
102, like CSE2 did before the accurate-portable-split, fixes this.
This used to be a feature before the accurate-portable split, I'm
just restoring it.
Previously, while the EXE itself had a unique icon, the window and
taskbar both used the generic 'small' icon, which the original EXE
only used for the window.
SDL2 gives us a way to assign separate icons to each, but it's a
little clunky: it's Windows-only, requires the icons be in .ico
format, and needs them to be embedded in the EXE as resource files.
Also, for some reason, SDL2 doesn't let us refer to them by name - we
have to use their numerical ID.
Funny story: so, there's a bugged TSC command in this file, which
causes it to try to read a flag beyond the end of the flag array.
If the memory it reads happens to be set to true, then it will
attempt to jump to an invalid event number, causing a crash.
Since I don't want to riddle CSE2's codebase with ugly compatibility
hacks, I think it's best to just fix the TSC file directly.
