Add setting for header proportion

[dnl-blkv]

How to Reproduce

1. Type in very long address, contacts or name

What Should Happen

1. There is a way to adjust header for long address or contacts (or name) by setting the address-to-name-to-contacts width ratio.

What Happens

1. There is no way to control the address-to-name-to-contacts width ratio and therefore the long address, contacts or name are wrapped

I was able to fix it by adding -0.5 before the center tag in the middle column.

Before:

\makeatletter
\newcommand\makeheader{
	\begin{center}
		\begin{tabu} to 1\textwidth { X[l,m] X[2,c,m] X[r,m] }
			\printaddress & \printname & \printcontacts \\
		\end{tabu}	
	\end{center}
	\vspace*{\afterheaderspace}
}
\makeatother

After:

\makeatletter
\newcommand\makeheader{
	\begin{center}
		\begin{tabu} to 1\textwidth { X[l,m] X[2,-0.5c,m] X[r,m] }
			\printaddress & \printname & \printcontacts \\
		\end{tabu}	
	\end{center}
	\vspace*{\afterheaderspace}
}
\makeatother

I'm guessing it depends on the name size but the number before the left/center/right tag defines the size to increase/decrease the columns.
