Microswitch (SD, the gated kind) support added. Turns out it's a trivial contact matrix (emulated).
Pedals - the switches that hang from a dedicated GPIO, like Shift or num/duplex/speed/online switches on TI 700 terminal - are now supported, too.
Looks like I've abandoned the hobby, so this is likely the last release. This accound is rarely monitored, so if there are questions (real questions only, please - do your homework first) - ping me on github.
