Added new flags to error checking of operands and function arguments.
This is so that a context can be developed that is more forgiving
about what can be put next to what. Such a context can NOT be used
for evaluation or answer checking, but can be used to generate TeX
output in more sophisticated situations.

More fixes for creating items in the corret context. Also added a
method for looking up the package associated with a particular Parser
class (for consistency with the Value->Package call).

Update to handle the fact that the Value package now includes the
context with all MathObjects. (This may still need some work.)

A first pass at making parser error messages localizable. The
Context()->{error}{msg} hash can be used to specify translations of
the standard messages. For example,
Context()->{error}{msg}{'Division by zero'} = "Don't divide by zero, dude!";
Context()->{error}{msg}{'Function '%s' has too many inputs'} =
"You passed too many arguments to '%s'";
(I didn't translate into another language, here, but you could do
that, too.)
The msg hash could also be used within answer checkers to make certain
answer messages more appropriate for the given type of expected answer.

Added an equality operator (not active initially) that can be used for
things like equations of planes and so on. I'm working on the answer
checker for that.
