settings.txt - simplugins variable needs to ignore trailing spaces

[jfgilliam]

simplugins = !Sounds.Shift

did not work because of a trailing space.

"Sounds.Shift = N" does not turn off the plugin either. You have use "Sounds-Shift"

This was reported by Chester Thompson.

I will support both names with a dot and with a hyphen.
