Make the sponsors note more flexible

It is now possible to define more than one sponsor which will be used
in a round-robin fashion.

+=head1 NAME
+
+Template::Plugin::Math - Plugin providing mathematical functions
+
+=head1 SYNOPSIS
+
+    [% USE Math %]
+
+    [% Math.sqrt(9) %]
+
+=head1 DESCRIPTION
+
+The Math plugin provides numerous mathematical functions for use
+within templates.
+
+=head1 METHODS
+
+C<Template::Plugin::Math> makes available the following functions from
+the Perl core:
+
+=over 4
+
+=item abs
+
+=item atan2
+
+=item cos
+
+=item exp
+
+=item hex
+
+=item int
+
+=item log
+
+=item oct
+
+=item rand
+
+=item sin
+
+=item sqrt
+
+=item srand
+
+=back
+
+In addition, if the L<Math::Trig> module can be loaded, the following
+functions are also available:
+
+=over 4
+
+=item pi
+
+=item tan
+
+=item csc
+
+=item cosec
+
+=item sec
+
+=item cot
+
+=item cotan
+
+=item asin
+
+=item acos
+
+=item atan
+
+=item acsc
+
+=item acosec
+
+=item asec
+
+=item acot
+
+=item acotan
+
+=item sinh
+
+=item cosh
+
+=item tanh
+
+=item csch
+
+=item cosech
+
+=item sech
+
+=item coth
+
+=item cotanh
+
+=item asinh
+
+=item acosh
+
+=item atanh
+
+=item acsch
+
+=item acosech
+
+=item asech
+
+=item acoth
+
+=item acotanh
+
+=item rad2deg
+
+=item rad2grad
+
+=item deg2rad
+
+=item deg2grad
+
+=item grad2rad
+
+=item grad2deg
+
+=back
+
+If the L<Math::TrulyRandom> module is available, and you've got the time
+to wait, the C<truly_random_number> method is available:
+
+    [% Math.truly_random_number %]
