I updated/improved/fixed the search module.

Now you can do an "advanced search" on selected modules.

- Published and archived news are indexed
- All forum messages are indexed
- All HTML pages are indexed

As cooper stated, it is easy for anyone making a module to make it searchable. When the search and index modules will be stabilized i will write a how-to. But basically there is very few to do so that it is indexed and if it is indexed then it is automatically searchable.

Any feedback would be greatly appreciated.
(it's all in the CVS HEAD)
