latex template: disable language-specific shorthands in babel.

Browse source 
Babel defines "shorthands" for some languages, and these can
produce unexpected results. For example, in Spanish, `1.22`
gets rendered as `122`, and `et~al.` as `etal`.

One would think that babel's `shorthands=off` option (which
we were using) would disable these, but it doesn't.  So we
remove `shorthands=off` and add some code that redefines
the shorthands macro.  Eventually this will be fixed in babel,
I hope, and we can revert to something simpler.

Closes #6817, closes #6887.
