Move 199[1-3]/ant and 2015/howe alt code

The unobfuscated code, which was put in deobfuscated/, has been turned
into alt code. In one case the already existing alt code was made alt2
and the unobfuscated code was alt. In the case of the ones with two C
files there, the one that did not require modification (to compile in
modern systems) were used as those are original.

In a few cases these changes suggested additional files: a test suite
Makefile for the alt code, a try.alt.sh script and maybe some other
things besides.

The bug status was updated for 2015/howe with a known bug: in particular
the test scripts do not work (at least not completely).

In the manifest all references (except for a file name that has not been
renamed - at least not yet) of 'deobfuscated' to 'unobfuscated': a minor
detail that might not matter much but it sounds ever so slightly better
(maybe). These other entries that had an entry_text change were
1995/garry and 2020/endoh2. Rebuilt .entry.json and index.html files for
this (and in the case of the moved code the index.html files also had to
be changed for that in addition to the Makefiles).
