This commit adds an index page for the multi-file HTML version, and
fixed a couple of casing issues (significant words starting with lower
case in headings).
While researching how to get the content from index-docinfo.xml into
the output, I came across the notion of a colophon, which is a good name
for the information in that file. I have consequently changed "Legal"
(which I never liked but couldn't think of a better term for at the
time) to "Colophon".

I made a complete editing pass plus another pass to see where I could add more links, both within the document and to other parts of Spring. The result was a thorough edit (though I'm sure I missed things, purely due to the size of the thing).
Remove extraneous white space and adjusted the length of non-code lines
to be as close to 90 characters (but not over 90 characters) as
possible.
Update a couple things I missed in the editing pass, too.
Closes gh-10892
