Add support for VM's and RDP

[ChristopherHaws]

I use parallels for VM's and Parsec for RDP and both of them seem to be tripling the scroll speed. My guess is that discrete scroll is telling the vm/remote pc to scroll 3 times and the host os is set to scroll 3 lines per scroll. Would it be possible to detect these types of applications and automatically switch the scroll speed to 1 line?

Thanks!
