Fix the recto/verso shuffle dance

The "ebook" option for memoir is a bit of a misnomer. You would think it sets
things up for electronic books but it actually sets up a traditional book with
the form factor of an e-reader. As a result of this the recto and verso
(odd and even) pages have different margins. I think it is a bit distracting
because the text shifts a little with each page. I don't know if this will show
up in the pull request correctly but the effect is:

This is alluded to on page 43 of the memman document but the author does
not really describe what is going on.

Provide backrefs in bibliography as in glossaries

The bibliography entries now provide a page backref just like the
glossary entries. It was supposed to be as simple as passing the
option `pagebackref` to hypreref. For some reason this caused a
problem with two URLs that did not escape the `#` character. Why
this was not a problem before is beyond me. I checked and the
links work--are not escaped--in the resulting pdf. Finally because
there were not enough latex build process artifacts this added a
Crypto.brf file to the build aftermath. Added an entry to gitignore
to ignore the Crypto.brf file.

I hope all is well in the land of the lakenois.
Remove ulem package

I have no idea why I thought this was a good idea. I have no
recollection of adding it.
