Rebuilding documentation for the 2.17.5 release; the docbook system on landfill proved to be broken.

* Bug 191971 - The guide incorrectly stated that you could resolve a bug via email
* Provide an example of a glossary term in the document conventions section

Full recompile of the docs so everyone can see what the current SGML docs actually look like in HTML.

Fix for bug 105365 - Hacker's Guide should be in SGML.  This will make it easier to do other additions to the hacker's guide.

same image, fixed these doc bugs (in no particular order):

known outstanding doc bug! Yay release.
Still many things to fix. Aren't there always?

dbschema.jpg file is changing, though.

in the latest restructuring of the Bugzilla Guide.

I added related information to the Bugzilla Guide, and
tacked in a couple of last-minute additions.  Also fixed the
annoying "Tip: HINT:" thing.

The README is now gutted, pointers to Guide.  Also some new sections added,
old ones fixed, and notes appended to deprecated sections I've not yet had
the heart to remove.

No text version of The Bugzilla Guide availabe yet, however.
