Add icon files present in the working content trees but not in SVN.
This might actually be a reversion, wherein changes made in SVN and
perhaps on the live tree never got fed back to development, as it is
not clear if these files are really needed. However, they're harmless
if not needed and important if used by any views.

Collaboa was updated to a newer Prototype library ages ago, but the
check-in got overlooked. Added standard blank template "application.js"
since a clean SVN checkout would otherwise lead to 404 errors from the
template inclusion of JavaScript ":defaults".

Delete frozen Rails version so that forum will run on whatever
Gem is indicated by its environment.rb configuration.

Delete empty directorys that get auto-created anyway.

CSS tweaks for the March 2011 update.

Explicitly specify a (slightly newer) Rails version so that the Forum
doesn't try to just run on whatever Rails gem is newest (it's not even
Rails 2 compatible, never mind Rails 3)! Related changes - remove the
PATH_PREFIX mechanism, since serving with Apache+Passenger gives
position independence without the PATH_PREFIX hack.

Relax restrictions on Textile use in forum posts.

Remove unnecessary static 404 and 500 status error pages.
Rely on autogeneration.

The Gem system has been updated. Gem's near-legendary backwards
incompatibilities then forced updates to the boot script for the
forum.

Rails and Gem upgrades for the March 2011 site update caused problems
with 'truncate' calls in the forum. Display name truncation in these
contexts is unnecessary anyway, so I've removed the truncate calls.

Another redundant file removed - see Revision #308.

Restructure main layout for March 2011 site redesign.

Remove edit-related fragments from the forum. To work with non-JS
browsers, the forum views were restructured to include an in-line
editor region which makes these extra parts redundant. Overlooked
in previous commits.

Fix Forum typing error that would cause empty search strings
to generate an error; fix bug on the same line which forced
a lower case database search, but forgot to coerce the search
string to lower case too.

Add a few more tools which were never previously brought under
source control. They don't expose any sensitive account-specific
information for the ROOL server.
