CTAN package downgrade: teTeX obsolete

[Robin Fairbairns]

Thomas Esser announced that he had stopped supporting teTeX some time
back.

Now that a new release of TeX-live has appeared, which has the potential
to be used in all applications where teTeX was previously preferred, I
have (with Thomas' agreement) moved teTeX to the obsolete tree on CTAN.
It will stay there for a while, as reference material.

Thanks are due to Thomas for all his work on his excellent distribution,
over the years.
