Update to register package

[Rainer Schöpf]

Matt Lovell submitted an update of his package register.

This package is designed for typesetting the programmable
elements in digital hardware, i.e., registers.  Such registers
typically have many fields and can be quite wide; they are thus
a challenge to typeset in a consistent manner.  Register is
similar in some aspects to the bitfield package by Reuben Thomas.

Anyone doing hardware documentation using LaTeX should examine
both packages.  Register requires a fairly recent version of
the float package.

This update provides a new boolean which can be used to test against
being within the context of a register diagram.  The accompanying Perl
script and module have also been modified to allow extraction of LaTeX
dependencies for Makefiles.

Thanks for the upload, I installed it in

   macros/latex/contrib/register
