Added explicit  loadMacros("MathObject.pl")  to
handle webwork questions which don't use math objects
for any other purpose other than graphs.

Changed plot_functions so that it uses the Formula MathObject to parse the
the function in

$f1 = qq! x^2 - 3*x + 45 for x in [0, 45) using color:red and weight:2!

instead of using the built in perl parser.

This allows things such as $formula=Formula("|x|");

$f1 = qq! $formula  for x in [0, 45) using color:red and weight:2!

to be evaluated. There should be no apparent change to old problems
since the Formula MathObject parser handles a superset of the builtin perl parser syntax.

This is not yet the most efficient method to have GraphObjects and
Formula's interact since the same string is being recompiled several times,
but it is a useful hack which preserves backward compatibility.

When making on-the-fly image names, replace periods in the student login
name to avoid problems with pdflatex.  Changed the replacement in set
names to use the same new trick (the old way had an infintesimal chance
of collision).  The new scheme is first double all instances of "Q".  Then
replace periods with "-Q-".

Allow default size of on the fly graphics to be set in global.conf, and make pop-ups of those graphs have windows closer to the size of the graph.  Also, pop-ups always make a new window - important for problems which make you compare two or more popped up graphs.

Made on the fly graph names use problem seed rather than psvn.  It is a better identifier for pages like SetMaker.  Also made image names workable for set names containing periods (for the day when set names are free to contain periods).
