LinuxSampler can not uninstall properly when there is an instrument editor
rmdir: /usr/local/lib/linuxsampler/plugins: Directory not empty
make: *** [uninstall-hook] Error 1
Yeah sorry, I have to admit that I never use "make uninstall" since I usually
use packaging wrappers that simply don't need to call "make uninstall" for
removing a package.
I just commited a fix. Thanks!
