8.0.0beta3 release documentation fixes for Tcl unbundling

These corrections against 8.0.0beta3 are for removal of the Tcl interface
from core. I found two left-over references in the top-level README to be
fixed, several in the top-level INSTALL and Installation chapter of the
manual (both generated from docs/src/sgml/installation.sgml, I think) and
one in the help text in configure.in.

In addition, please delete doc/man1/pgtclsh.1 and doc/man1/pgtksh.1 from
the distribution, since these commands are no longer included.

Here are my suggested changes. Since the target files are highly
visible, I assume you will check this over very carefully and rewrite as
appropriate...
