Add unobfuscated code from @SirWumpus

The entries 2004/hibachi and 2005/mynx have unobfuscated code now.

2004/hibachi has a configure script that is used along the lines of the
original entry (with some adjustments and fixes) and the hibachi.alt.c
had to have ctype.h included too. The directory src/localhost was copied
to src-alt/localhost but the rest of src/ was from Anthony. The Makefile
had to be updated to build this version.

2005/mynx does have a configure script but it is, just like the original
entry, unused and so the unobfuscated (in source-alt/) is also unused.
The mynx.alt.c was changed to mynx.alt2.c and the unobfuscated code was
made mynx.alt.c.

Updated manifest, rebuilt .entry.json and index.html files.

After a question is answered and taken care of (in one of 199[1-3]/ant -
not sure which one) issue #2513 can possibly be closed as complete
(though the manifest updates will have to be looked at more when 2004
and 2005 are reviewed).
