added geometry support for mudela-book

[Tom Cato Amundsen]

I added support for the geometry package today. All options
supported by the geometry package should work, but I'm sure
there are plenty of ways to confuse mudela-book. Please
report any problems to this list.

landscape package is gone in this version, but you
can get landscape with
\usepackage[landscape]{geometry}

Also, commenting out mudela-blocks like this
%\begin{mudela}
% BLABLA
%\end{mudela}
should work as expected.

Attached a testversion of mudela-book.
