Version Control With Subversion Source

- We have differences not diffs
- Change semantics of switches to --long (-l) ARG
- Make switches talk in the 3rd person
- Make capitalization consistent in some places
- Make install, not war
- Use 'form', not 'sample' in Descriptions
- We have directories, not dirs
- We have properties, not props
- We have revision properties, not revprops
- Relocate log --incremental example

* /doc/book/book/ch08.xml: More cleanup.
