Allow config file (alternate sbbsecho .ini file) to be passed on cmdline

Back in the day, some sysops used to use multiple SBBSecho configuration files.
Nobody seems to do that these days, but its certainly a viable solution (or
should be) for multiple FTNs on a single BBS. Anyway, this enhancement allows
BinkIT to use an alternate SBBSecho configuration file (though it must still
be located in the ctrl dir).
