ROOL change: The Radiant Textile help page includes a hard-coded path
reference to an image. The context makes it hard to generate this with
Rails dynamically, so just update this hard-coded reference to match
the location of the actual Radiant image resources on the ROOL server.

Changeset #378 completes check-in of Radiant 0.9.1 in its gem form, as installed
originally, except for the removal of vendor/RedCloth in Changeset #375. Now for
more ROOL customisations - gem incompatibilities again this time. The I18n gem
in use centrally only supports new-style token substitution syntax so update the
English messages file accordingly.

Various other files are in the GitHub sources, but not in the distributed Gem.
Many of these are Git specific or temporaries which probably should not have
been put into Git in the first place.

Various files are in the gem, but apparently not in the source distribution
on GitHub. These have been copied in from the working gem.

The '.gemspec' file says how to build a gem, so it isn't part of
the final distro.

ROOL changes - remove local copy of RedCloth; use the central Gem.

Remove Git control files, since this is SVN.

Initial import of Radiant 0.9.1, which is now packaged as a gem. This is an
import of the tagged 0.9.1 source checked out from GitHub, which isn't quite
the same as the gem distribution - but it doesn't seem to be available in an
archived form and the installed gem already has modifications, so this is
the closest I can get.

Reinstated automatic section numbering JS code from I2. Although
manual numbering isn't possible since JavaScript isn't allowed
inside pages, the automatic code works fine.

Changeset #370 influenced forum and article lists. I decided it looked
better the old way so this new Changeset adds more specific table style
rules to catch those specific cases.

NetSurf improvements with images. Limit width of PRE blocks. Improve
table related CSS to prevent accidental overriding of the main stylesheet
and improve appearance of tables within posts.

Improve appearance of nested <blockquote>s, as seen at:

Log for Changeset #367 is inaccurate. This change patches around invalid
XHTML markup written directly into pages, which would cause exceptions if
used as part of a diff. The post-Textile-processing data is run through
Hpricot to clean it up and a warning is included in the diff. If further
exceptions occur, the user is told that the diff can't be shown, rather
than just given a 500 error.

This new version of the file just tidies up the location of the 'require'
for Hpricot.

Final file in the Instiki changes for 0.19.1 and ROOL customisation;
looks like this got missed out in Changeset #344/Changeset #345. It
is part of the original 0.19.1 distribution.

Hub integration.
