[BC BREAK] rater/core/insurance (_premium_): Add zero and negative assertions 

This is a BC break since this generates assertions by default.  To maintain
BC, set `@allow-zero@' and `@allow-negative@' to `true' in existing template
applications.

* core/insurance.xml
  (assert_ignore_premium_zero, assert_ignore_premium_negative): New params.
  (_premium_): Generate assertions.
    [@allow-zero@, @allow-negative@]: New params.

Some notable TODOs:
\begin{enumerate}
\item Support scalar results;
\item Fail on zero premium unless explicitly stated;
\item Fail on negative premium (use a credit template); and
\item Support scalar results; and
\item Rounding direction (currently only nearest).
\end{enumerate}
\todo{Template to abstract these {\tt rate-each} generation
templates.}
