--enable-perl* -> --with-perl*. Added a new libfe_perl which handles /SCRIPT

commands. /RUN -> /SCRIPT LOAD, /PERLFLUSH -> /SCRIPT FLUSH, /PERL ->
/SCRIPT EXEC. Added /SCRIPT UNLOAD, /SCRIPT LIST. Lots of cleanups.

filename_complete() has extra argument for "default directory" which is
searched if no path is given when completing.
