Fix how innfeed handles the number of connections when using -x #184
Description
When using the -x option, the config file entry's initial-connections field will be the total number of connections created and used, no matter how many big the batch file, and no matter how big the max-connections field specifies. Thus a value of 0 for initial-connections means nothing will happen in -x mode.
