Add deobfuscated versions of 199[1-3]/ant

Anthony/@SirWumpus kindly provided these files. The source code and
their Makefiles are in a deobfuscated/ subdirectory (for each of the
three entries) but running make alt
from the entry directory works. It uses the deobfuscated version's
Makefile but copies the compiled binary to the entry's directory to keep
things clean (deobfuscated code separate from the entry) to simplify
using the deobfuscated versions.

Entries that had a test suite Makefile have a new one for the
deobfuscated code and a try.alt.sh script was added to 1992/ant and
1993/ant but the entry_text is a bit different than the usual to
indicate that it's the deobfuscated version.

It might be that the way this is done should be reorganised some but
that can be decided on later.

The entries from 2004 and 2005 have not yet been added because some
decisions have to be made as those are the ones with a configure script.

The manifest was updated and the .entry.json and index.html files were
updated. It is not clear yet if the inventory_order is right but that
will be looked at in the next day or two.

Thank you Anthony!
