Use backslashes instead of forward slashes on Windows for part of the
path to the proxy

Buffs.on_mood_changes.register/unregister -> append/remove
update_mood Handler: add old_mood/new_mood parameters

Also add some more logging

For Sims 4 patch of 13 Nov 2018 (Get Famous)

Other compilers (including MingW) would cost a lot of effort to support,
as the LogitechLED SDK is provided as MSVC dll.

Easier to reuse for whoever wants to. Also cleans up the main CMakeLists
file.

This means we can remove Logitech's SDK from the repo again

- Handle eof by quitting
- Clear extraction errors

This prevents the proxy from going into an endless loop attempting to
read a failed stream, if something goes wrong.

- New color structure (tuple) and scaling is used in internal API
- Fix function name of logiled_stop
- Restart logiLedService in stop/start/restart commands
- Fix logiled.override cheat (Wrong commandType was used)
- Fix logiled.test Sim name printing (now on one line, no empty brackets
shown in output)

The mood_led_changer now uses Sims-based rgba tuples (see sims4.color),
putting the weird scaling to the Logitech class (where it belongs)

Tabs -> spaces

Added CMake code to pack the ts4script file. Some restructuring was done
and internally used paths were changed to correct these changes.

All components are now split up in separate files too, within the
logiled module.

If it didn't start for whatever reason (possible with reloads), it won't
throw an exception when quitting either.

- CustomGameService is started/stopped as a game service
- Using on_client_connect/disconnect the changer now automatically
starts as a game is loaded

LogiLed is now a global service that anything can hook into; the mood
changer is just one of its clients (and currently the only one).

Effectively quits the proxy

Uses (customized) injector by scripthoge from ModTheSims.

- Proxy no longer runs in a separate thread, but is used from main
thread directly.
- CustomGlobalService class can be inherited to inject a mod as global
game service. It's started at some point after getting into the main
menu (after all other core services are started) and will be stopped
correctly when quitting the game.

Handling the game quit requires a special injection, because (in the
current Sims 4 version anyway) it seems the core services are not
stopped properly.

- Still messy (everything in a single file)
- Proxy window shows up (not hidden yet)
- Proxy doesn't quit on game exit yet (that's why the window still shows
up)
- Mod doesn't hook into zone load yet, so requires starting manually
through a cheat

Positive notes:
- It does track Sims moods
- It does apply the colors correctly
- It's reloadable
