for other types of search engine plugins if wanted, and also opening up a
lot of new possibilities for other kinds of plugins later
some notable changes along the way:
- lots of new hook types: cgi, render, delete
- wrapper files fixed to support config strings with newlines in them
- HEADERCONTENT in page template useful for plugins. Probably needs to be
expanded to more such for other places plugins might want to add content.
- remove unnecessary wrappers field from config info stored in wrappers
to pave the way for adding other RCS support. This also changes the
setup files, where before they had svn => 1 or svn => 0, now they have
rcs => "svn" or rcs => "".
* Add a debian/NEWS file with upgrade notes.
* Load whatever rcs module is specified, so new ones can be just dropped in
as plugins and work.
* Add some basic docs about writing RCS modules.
