Added syntactic sugar for pop_up_lists.
A common situation is that a problem includes a short multiple-choice question along with other answers. Often, these questions are written as fill-in-the-blank where the student is told a list of legal words to put in the blanks. The idea is to make it as simple as possible for problem writers to replace the fill-in-the-blank with a drop-down list of alternatives.
So, now the text of a problem can contain
is the function increasing on [0,1]? \{ pop_up_list(['?', 'yes', 'no']) \}
instead of
is the function increasing on [0,1]? \{ pop_up_list('?' => '?', 'yes' => 'yes', 'no' => 'no') \}
The result is checked with something like
ANS(str_cmp('yes'));
Existing problems are unaffected since the added syntax uses a reference to a list (the extra square brackets).

This adds wiring to the pg side for special bits of html to be included before/after the body of a problem. You also need to update global.conf (and probably want to update Tasks.pm).
A commented out example in global.conf.dist shows how to use this to produce boxed problems a la the Union College server. In this approach, the added parts are not used for problems rendered in the Library Browser or Problem Set Detail.
This addresses bug 817. This solution may not be suitable for inclusion of needed bits for modes such as asciimath or tth because the those bits of html are probably needed for display in the Library Browser. It is hard to distinguish bits which are always wanted, and those which are only wanted for use by Problem.

Removed some unused lines and comments.
Removed unnecessary spaces from around answer-rule-extension rules,
and made the TeX version of this rule be based on the width, as is
the case for ans_rule.

Removed skip and rule from problem header generated in TeX mode here,
and let the snippets handle it (they were producing redundent rules).
Also removed some unwanted spaces in htmllink().
(Accidentally committed experimental change to dangerousMacros.pl, and
don't know how to prevent it at this point, so I'll commit a change
back to the original in a moment.)

Fixed a bug in jsMath mode where it would not display < (when it looked like
part of a tag).
Also, removed unwanted spaced around input box.

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.

Use the new PGsort which uses a true/false compare (e.g. < or lt )
rather than a -1,0,1 compare (e.g. <=> or cmp ).

Modifications to PGbasicmacros and PGanswermacros which check whether a function answer
is the same as the function answer submitted previously. Gives warning message
if the same incorrect answers is submitted twice in a row. The functions must
both compile in order to recognize that they are the same answer. Two syntactically
incorrect entries will not be recognized as equivalent, even if they are in some sense.

Added convention to beginproblem that point value of "" means that we don't
print the point value at all. It will also supress printing of the filename
if someone is supposed to have filenames printed, which is appropriate for
the one known time this convention is used.

Made changes to the check box macros so that they will remain
sticky when more than one check box is checked.
Involves splitting a null separated string ( or perhaps converting
a reference to an array). uses a new subroutine contained_in(elem,
array_or_arrray_ref_or_null_separated_string)
this resolves part of bug #400

If LaTeX formula ends in a backslash after removing training spaces,
then we removed too much space, so we add a space to the end of it so
it ends '\ \)'.

Made changes to rh_sticky_answers so that they
are addressed correctly.
Long term I would like to remove all
references to main:: except for those
in the init routines. The references
can be replaced by a locally defined
pointer to the value in the current safe
compartment.
This procedure should make it easier to
maintain the macros. All references to
global variables will occur in the init
routine.

Added $ to PG_random_generator in the subroutine SRAND. Why it worked
before as a bare word is anyone's guess. Now that $PG_random_generator
is a local variable the bareword no longer works properly.

I've added ans_array and ans_array extension and moved answer_matrix here since this is probably where it should be with all
the other answer blank methods. I still have to comment the code.
