Further tidying - removed some sidebar attributes that are already
in the global stylesheet and don't need duplicating in the Typo theme.

Removed large font size on code items - it looked silly. Got rid of
redundant sidebar item already contained in the global stylesheet.

Fixed mail notification messages to generate correct URLs regardless of
whether or not the controller is called from the application root or
"admin/". I'm not sure if the solution is entirely valid - I get the
feeling that the fix should be in the routes somewhere - but using a
"/" in front of the controller name to override url_for defaults, seems
to produce a correct result after several tests.

Improved news behavior with better handling of specific filter types
for the page part including the news tag.

Upgraded Lightbox to latest version from the Lightbox Home page at
"http://www.huddletogether.com/projects/lightbox/". Customised the
Lightbox CSS. Tweaked wording in 'theme' partial for RISC OS Open
theme. The Lightbox controller was trying to generate URLs correct
for any location of the Rails application but the attribute it was
trying to use did not return the expected string; changed to use
another blog-specific property that generates the correct result.

Removed old migrations. Typo 4.0.0 installation now tested and
generally working (the odd URL going from document root here and
there, not much else wrong). The database migrations worked OK
once the files deleted in this revision had been removed from
the working copy.

Reapplied changes to Typo 4.0.0 from previous version in order to
configure it for use on the RISC OS Open site. Hopefully, the RISC
OS Open theme can be sorted out so that it works with no further
core changes.

Note that this configured v4.0.0 installation has not been tested.

Deleted lots of files that aren't in the 4.0.0 distribution and
shouldn't be in SVN. Some of these may be added later for theme
support reasons. By far the biggest removal is the vendor copy
of Rails, since Typo now runs on the centrally installed Rails
1.1.4.

Added new Azure tests for Typo 4.0.0.

Start of upgrade to Typo 4.0.0, the latest stable release since
2.6.0. Note test/mocks/themes/azure changes from a file to a
directory, so the file has been removed in this revision and
the directory will be added in the next revision.

Removed redundant .htaccess file.

Corrected spelling of "Textile" (one 't' in the middle).

Corrected spelling of "Textile" (one 't' in the middle). No longer have
any need for the 'removed_from_vendor' data, so deleted it; it will remain
in the SVN history in case it is ever needed again in future.

"New article" notification e-mail messages contained a link to the wrong
controller for content administration. This change was meant to have been
checked in some time ago but got lost during the migration to SVN. While
this fixes Ticket #40, user management in Typo will need revisiting for
single sign-on - does the whole user infrastructure get replaced, or do
admin users stay as they are, but "public" users go through SSO and have
a different set of options available to them?

Updated version of the News behavior that removes the simple-rss
dependency by using core RSS instead and now handles SlashDot on
Textile filtered pages by escaping "~" characters in URLs.
