New script for Alesis PerformancePad

[BufoBufo]

Just in case there's another PerformancePad owner left who'd like to use it in Bitwig..
Here's a little script providing what's missing in the device: configurable gate time, note remapping to C1..G1 and some velocity curves.

It might work for the PerformancePad Pro as well - feedback is welcome.
