Add benchmarks for running tail-recursive and non-tail recursive procedures.

Add a regression test for bug #1552426, which crashes.

Add some tests that are intended to test the evaluator.

Add function comment for parser_iterate().

Add a phony target to copy the HTML to a directory that is suitable for publishing on SourceForge.

Move the values of "html.stylesheet" and "html.stylesheet.type" XSL string parameters from the Makefile to the XSL files, now that I know how to specify them. I would have done this from the beginning, but I didn't understand the difference between specifing a number template parameter and a string template parameter.

Remove leading whitespace from within <programlisting> tags.

Extraneous whitespace became important when I started using CSS for the HTML output. Now that I shade examples in grey, any extraneous newlines is very apparent (and looks amateur-ish).

Note some of the improvements that were made to the online manual.

Change the way the .PDF file is generated to use XSLT and FO, instead of using jade and DSSSL.

This fixes bug #1432655; logohelp.pdf has strange indentation of examples

Make it so that the HHC doesn't show the root. Now, each chapter is shown at the top level. In addition to saving the user a click, the TOC also auto-updates to whatever the user clicks on in the index. This is a major improvement.
