Christian Lademann's contribution: new capabilities in smb.conf.

'<' and '|' characters indicate read file and execute command respectively,
and feed the output into the parameter (!!!).

'<$' and '|$' means run standard_sub_basic() on them.

this is going to be fun to document in smb.conf.5....

also, Christian created a new "online" service parameter.  services can
be taken "off-line"....
