txt2html

A bug where #bold# interpretation was rendering
#anchor links incorrectly was fixed.

The --instring option was added to the txt2html
script, which enables one to process a string
instead of a file. The --instring, --inhandle, and
--outhandle options were added to
HTML::TextToHTML. The --instring option works as
described above. The --inhandle option enables one
to pass in input file handles to process. The
--outhandle option enables one to pass in an
output file handle.

The global links dictionary is now built-in, not a
separate file. This will cure the persistant
installation hassles related to that file. The
run_txt2html method was removed, as it is not
needed. The documentation was updated.

The speed of the program was greatly improved.

Another fix in installation.
