Run rlog commands as pipe so we can cgi.escape(output).
Added self.escape(), like cgi.escape() but also escapes " -- for use
as double-quoted attribute values inside HTML tags.
Fix complains from Mark Lutz: HTTP_HOST is not always set.
- Add translation of *foobar* into <I>foobar</I> (but not inside <PRE>).
- Optimization for the translation: only translate when @ or / or * seen.
- Add some layout to front page lay-out.
- Fixed broken HTML in edit form that swallowed <BR> tags
- Removed "another one" link in roulette, replaced with "use Reload" message
- show() now has edit=1 by default; changed all calls
- Display last-changed date, author, email when present and edit=1
- Added back pointers at bottom
- Added a copy of the bootstrap script at the end of the file
- got rid of the separate search page
- added an index (lists the questions with links to the answers)
- add a mechanism to add new entries
- add a way to list most recently edited entries first
