s_conf: Don't leak strings when loading default conf

Browse source 
This change prevents conf strings from being leaked when resetting the
conf to default prior to a rehash. Additionally, some default strings
are now rb_strdup'd into the ConfigFileEntry structure after loading the
conf so that they aren't allocated and then immediately freed by the
conf loading process.
