Changes to Wikit Formatting Patches between r7 and r15

I've backported the current Wikitcl formatting to the version I use.  Additionally, I've imported some of Steve R.'s patches.  The patch is here:
http://www.rkeene.org/projects/info/resources/projects/wikit/formatting/wikit-betterformatting-4wikitcl+stever+rsk.diff --> http://www.rkeene.org/projects/info/resources/projects/wikit/formatting/wikit-betterformatting-7wikitcl+stever+rsk.diff

The changes to the Wikitcl "format.tcl" can be found here (this is probably not useful to anyone):  http://www.rkeene.org/projects/info/resources/projects/wikit/formatting/wikitcl-format-3wikitcl+stever+rsk.diff

The major changes in this patch are:
   * The ability to create nested lists (ordered or unordered)
   * The ability to change the footer for the web page
   ** In the "Web Settings" set FooterText to append something to the existing footer;
   ** Set FooterTextReplacement to replace the text entirely, using command and variable substitution ($Search translates into a link to the Search page and the text "Search -", for example)
   * The ability to create links to other sites without being a numbered and bracketed link.  The preferred format is URL%|%Text%|%, but alternatively you can use [[URL | Text]]
   * The ability to include one Wiki page in another.  The syntax is [[@include Page]] on a line by itself.
   * The ability to put comments in the text of a Wiki entry.  The syntax is three hashes (###) at the beginning of the line.
   * Slightly improved CSS for links
