Merged 438:439, 440:441, and 442:457 from trunk/ to branches/1.1/, mostly major work done for 1.1.1 release.

- Various documentation updates
- Fixed fatal error in benchmark scripts, slightly augmented
- As far as possible, whitespace is preserved in-between table children
- Configuration option to optionally Tidy up output for indentation to make up for dropped whitespace by DOMLex (pretty-printing for the entire application should be done by a page-wide Tidy)
- Sample test-settings.php file included

Unrelated unmerged edit: removed irrelevant 1.2.0 release notes, those only exist in the trunk.
