ps move: allow to configure mouse move handler buttons

[Megamouse]

• Adds a new configuration dialog for "PS Move (mouse)" to the usb device settings
• You can use this to configure the previously hardcoded mouse buttons
• Combos are still possible with the extra button configuration
• Add empty dropdown item to usb device settings. This can be used to clear the button.

You can use this to configure the previously hardcoded mouse buttons

Here I thought that was implemented already

And you called me an epic troll. I just thought you didn't rename the dialog after adding reconfigurability to this dialog for mouse handler
Now I see, my bad

Yes, you could already do that to some extent. But those are not the same dialogs.
You still have to configure the mouse settings first, then use those to configure the ps move input.
The main difference is that you had to magically know what's what before, while you now see what you're mapping to which ps move button.
I only added the combos because I think they might be useful for lightguns for example.

That being said, it's still a bit annoying to set-up.
So I'll be adding a little hint so users know which buttons they configured in the mouse dialog

would it be possible to allow keyboard assignments inside of this dialog? for example since my light gun only has 3 buttons, i would like to assign 1 key to start or L key to Square for use as a time crisis pedal . the combo buttons are working great though, finally able to bypass calibration screen cleanly
