Change xlines to store spaces as \s.

Browse source 
Spaces in xline.conf files are changed to \s in memory
and recognized on unxline, but are not changed in the
file. New xlines are added to xline.conf files with \s.

xline.conf written by this commit or newer will not work
properly with charybdis older than 1124:131254925f32 (which
introduced \s support in match_esc()).
