Upstream changes:

• Enhance /reports to support event type filtering.
• When cloning a repository, the user name passed via the URL (if any) is now used as the default local admin user's name.
• Enhance the SSH transport mechanism so that it runs a single instance of the "fossil" executable on the remote side, obviating the need for a shell on the remote side. Some users may need to add the "?fossil=/path/to/fossil" query parameter to "ssh:" URIs if their fossil binary is not in a standard place.
• Add the "fossil blame" command that works just like "fossil annotate" but uses a different output format that includes the user who made each changes and omits line numbers.
• Add the "Tarball and ZIP-archive Prefix" configuration parameter under Admin/Configuration.
• Fix CGI processing so that it works on web servers that do not supply REQUEST_URI.
• Add options --dirsonly, --emptydirs, and --allckouts to the "fossil clean" command.
• Ten-fold performance improvement in large "fossil blame" or "fossil annotate" commands.
• Add option -W|--width and --offset to "fossil timeline" and "fossil finfo" commands.
• Option -n|--limit of "fossil timeline" now specifies the number of entries, just like all other commands which have the -n|--limit option. The various timeline-related functions now output "--- ?? limit (??) reached ---" at the end whenever appropriate. Use "-n 0" if no limit is desired.
• Fix handling of password embedded in Fossil URL.
• New --once option to fossil clone command which does not store the URL or password when cloning.
• Modify fossil ui to respect "default user" in an open repository.
• Fossil now hides check-ins that have the "hidden" tag in timeline webpages.
• Enhance /ci_edit page to add the "hidden" tag to check-ins.
• Advanced possibilities for commit and ticket change notifications over http using TH1 scripting.
• Add --sha1sum and --integrate options to the "fossil commit" command.
• Add the "clean" and "extra" subcommands to the "fossil all" command
• Add the --whatif option to "fossil clean" that works the same as "--dry-run", so that the name does not collide with the --dry-run option of "fossil all".
• Provide a configuration option to show dates on the web timeline as "YYMMMDD HH:MM"
• Add an option to the "stats" webpage that allows an administrator to see the current repository schema.
• Enhancements to the "/vdiff" webpage for more difference display options.
• Added the "/tree" webpage as an alternative to "/dir" and make it the default way of showing file lists.
• Send gzipped HTTP responses to clients that support it.
