Changes to "Wikit Revision History" between r1 and r2

Changes to Wikit Revision History between r1 and r2

Small patch to enable revision history to be stored in the Wikit TKD file:
* http://www.rkeene.org/projects/info/resources/projects/wikit/revisions/wikit-revisions-1rsk.diff

This has only been tested with the CGI interface.
----
I also created another small patch [http://www.rkeene.org/projects/info/resources/projects/wikit/style/wikit-style-3rsk.diff] that allows you to use a style-sheet, and the CGI without a wrapper CGI. Just name the style sheet "wikit.css" and put it in the same directory as the CGI.
