Hide the "Tip", "Warning", and "Note" titles in their respective
blocks. The icons serve the purpose well enough.

Add a warning about svndumpfilter literal path interpretation as
requested by Tigris.org user Jeff C <jeffc@...> in Subversion
issue #1853 (http://subversion.tigris.org/issues/show_bug.cgi?id=1853).

* src/en/book/ch-advanced-topics.xml
Add a useful note about externals, partially suggested by Eric Hanchrow
<offby1@...>.

* src/en/book/ch-repository-admin.xml
My experience with BDB repositories is that they are more than just
slightly larger than FSFS ones, and grossly larger if logfiles are
present. Update the comparison table accordingly.

Incorporate changes from Ben review. Thanks Ben!

* book/ch-basic-usage.xml: Tighten up chapter even tighter.

* src/en/book/ch-repository-admin.xml
Some tweaks based on Fitz's review.
