Extended this context to handle multivariable polynomials.  So you can
use things like

	loadMacros("contextLimitedPolynomial.pl");
	Context("LimitedPolynomial")->variables->are(x => 'Real', y => 'Real');
        Context()->flags->set(singlePowers=>1);
	$f = Formula("1 + x + y + 2xy + x^2 + y^2");

Fixed a problem where things like x+4x would be accepted even in
single-power mode (the initial x was not being identified as a single
power of x correctly).

Make error messages potentially localizable (by making them use
sprintf-style strings rather than variable subtitution).

Implements a Parser context in which only polynomials (of a single
variable) can be entered.  Only sums of multiples of powers of the
variable are allowed to be entered (though the coefficients can
contain mathematical operations).  An optional flag lets you specify
that only one term of each degree is allowed, so the student would
have to combine 1+x+x+x^2 to get 1+2x+x^2 in that case.
