Version Control With Subversion Source

Edit, organize, migrate, and introduce the Troubleshooting from what
we currently have in the project FAQ.

* /trunk/doc/book/book/appc.xml: Add content.

* doc/book/README
Updated heap allocation and fop.sh invocation suggestion to take
FOP_OPTS into consideration.

Lots of picky little fixes:
- 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.

De-note-ify the note-diddly-note note.

* /doc/book/book/ch08.xml: Undo excessive use of 'note'.

Add some JVM memory hints from Michael Price.

It's "run-fop.sh", not "find-fop.sh".

Undo accidental commit

Merge filesystem changes that have occured on trunk since branch
creation into the branch. That's revisions 4527-4978 of svn_fs.h and
the libsvn_fs tree.

Also:

* subversion/libsvn_fs/tree.c
(txn_body_copy): Fix compiler error (need const for svn_fs_id_t's).

Add table data style stuffs, and a note about font selection.

* doc/book/book/styles.css
Make a quick first-pass at beautifying our HTML output. Loving the
sidebars, Warnings, and Tips...
