Previously, if the user tried to submit content which was
malformed utf-8, Instiki would complain loudly to him.
A slightly more user-friendly approach was suggested by
the latest Rails 2.3.4, and a conversation with Sam Ruby
(who suggested some improvements).
Now, instead of complaining, we remove the offending bytes,
leaving a well-formed utf-8 string, which we pretend is what
the user meant to submit.
Added the ability to rename existing pages.
[[!redirects Some Page Name]] redirects Wikilinks [[Some Page Name]] to
the current page (assuming "Some Page Name" does not exist).
Real pages trump redirects (though this may change, depending on
user feedback).
Be a little gentler in recovering from Instiki::ValidationErrors, when saving a page.
Previously, we threw away all the user's changes upon the redirect. Now we attempt
to salvage what he wrote.
Updated to Rails 2.2.2.
Added a couple more Ruby 1.9 fixes, but that's pretty much at a standstill,
until one gets Maruku and HTML5lib working right under Ruby 1.9.
