update index.html and .entry.json per recent manifest changes

Every index.html file (for entries) was updated as the tarball download
description was changed to 'download entry source' (though I think this
is a mistake as the C file is described as 'entry source' so it's
ambiguous - that might be fixed soon or it mightn't be until some other
changes are made that need a manifest update).
