[Building Sakai] Filtering Site IDs in tool content when duplicating sites.

[Matthew Buckett]

Does anyone have any opinions about the patch attached to:

https://jira.sakaiproject.org/browse/KNL-737

It creates a service which tools can use to filter their HTML content
for references to content contained in Content Hosting. The idea is
that when content is being duplicated between sites any links relative
to the old site should be re-written to use the content in the new
site and the content should also be copied across. This is because
when duplicating content between sites it maybe that the Resources
tool isn't being duplicated. Some existing patches did this by just
filtering all instances of the site ID, but doesn't work when the site
IDs are more meaningful as then may exist in the content outside of
URLs.

I've also got patches to tools (eg announcements) which switch to
tools to using this new service.
