Update the TEA-based approach for accessing Pltcl under tclsh on Windows platforms.  I have dropped the old Windows method which was completely broken and replaced it with a method which slightly adapts the Unix way of accessing PLtcl by using the known different locations for the dll's in the Windows case.
Update the TEA-based approach for accessing Pltcl under tclsh on
Windows platforms.  I have dropped the old Windows method which was
completely broken and replaced it with a method which slightly adapts
the Unix way of accessing PLtcl by using the known different locations
for the dll's in the Windows case.

Tested by Alan W. Irwin <airwin@users.sourceforge.net> on
MinGW/MSYS/Wine by running the tclsh demo given by
examples/tcl/README.tcldemos by hand for a few examples and also by
running the test_tclsh_standard_examples target.
