* Rewrote the input handler
Added support for dinput and xinput, full keyboard slider cell binding (#127), hold-takeovers, button alternation and auto-sliding (PS4 behaviour). See segatools.ini for a detailed description about everything.
* Split touch handling into backends and added Wintouch touch emulation
Now you can use actual touchscreens as well as mouse emulation was not the greatest when trying to use an actual touchscreen.
* Fixed input issues
gamebtns was always uninitialized, so good luck trying to do anything. How did nobody ever complain about this? lol
* Fixed resolution issues caused by chaining both gfx hooks
The diva-specific hook is the only one we need. Stacking both has strange effects.
* Added support for the MITSUBISHI CP9550DS printer
Q: Why?
A: /shrug

I am not particularly good at this game (or the pass requirements are insane, 23+12 misses out of ~550 is a fail!?), so if someone could test how this feels as opposed to the PS4 version, that would help a lot!

Also something that happens but that I can't reliably reproduce is that my aime card reader randomly becomes NG after a dozen game starts until I delete eeprom.bin.
If that is the case, the only packet sent is SEND_HEX_DATA.

## Summary
Adds a unified mechanism for locating third-party IO DLLs through environment
variables, on top of the existing per-game `[xxxio] path=` INI setting.
## Changes
For each IO DLL, the path is resolved in this order:
1. The section-specific INI value, e.g. `[mai2io] path=`.
2. The section-specific environment variable, e.g. `SEGATOOLS_MAI2IO_PATH`.
3. `SEGATOOLS_IO_ROOT` joined with the default IO DLL filename, e.g.
`%SEGATOOLS_IO_ROOT%\mai2io.dll`.
4. Empty path, which keeps the built-in IO implementation (unchanged default).
INI and environment-variable paths are run through Windows environment-variable
expansion, so values such as `%SEGATOOLS_IO_ROOT%\mai2io.dll` are valid in the
INI directly.
