Title: Load filter scripts without enabling them at once

By applying this patch, ettercap now can load filter scripts (-F)
without enabling the newly loaded script at once; to achieve this, the
flag ":0" is appended to the filename of the filter script, allowing
multiple scripts to be loaded and enabling them individually by using
the interactive interface.
