[panda-users] Plugin crash

[Brendan Dolan-Gavitt]

Asidstory needs to have a plugin loaded that specifies what OS is
being used in the replay, so that it can read information like process
names and PIDs. Running

~/panda/qemu/x86_64-softmmu/qemu-system-x86_64 -m 1024 -replay spotify
-panda win7x86intro -panda asidstory

should work.

This does need better documentation! We are working on that :)
