Change references of 'alt code' to 'alternate code'

This was done by:

    sgit -e 's/alt code/alternate code/g' . ; git co tmp/OLD_manifest

as well as updating the tmp/manifest.numbers spreadsheet and exporting
to the CSV file (though that would not strictly be necessary).

The way this works means that the update manifest script does not need
to be run as it sgit(1) touched the .entry.json files (any that needed
to be updated) and so would any index.html files. An example for both
.entry.json and index.html files being modified due to manifest is
2012/kang.

Numerous Makefiles were updated, any try scripts that had 'alt code'
instead of 'alternate code' and README.md/index.html files (unrelated to
the manifest as 'alt code' was used in other places too) and obviously
the manifest.numbers spreadsheet.

However to be safe I will do a run of the manifest script in a bit even
though it should not be necessary. If no commits are made it means all
is good and if any commits are made for the manifest it means that I
did not think of something (or else I made another change after this).
