Support axis value input from buttplug #207
Description
Requires fake/MITM buttplug server, probably needs to be added into Buttplug.NET first.
Where to put the UI for this? Make internal plugins?
Need to be able to enable/disable them. Since they are internal we can save settings into main config.
The internal plugins could be used for other inputs.
The plugins would have to use shortcut actions/motion transitions which is meh.
Or implement #121 instead.
