Changed loadMacros() to use search for amcros files via a
user-cusomizable path of directories. This is specified in the
global.conf file, and can include any number of directories.
The path can include "." to mean look in the .pg file's directory.
This makes it possible to store special macros files with the code
that uses them.
By default, the path is ".", the course/templates/macro directory,
then the pg/macros directory (in that order). This duplicates the
current behaviour, except for the ".", which is new.
You must also make the updates to the global.conf,
webwork2/lib/WeBWorK/PG.pm, and webwork2/lib/WeBWorK/PG/Local/pm files.

Updated i(), j() and k() functions to check if the Parser is loaded,
and if not, return a value that will cause perl to report a better
error than calling the parser outside of its normal context.
Since the current answer checkers call perl directly to evaluate their
expressions, when a variable is used by a student that is not a
variable used by the checker, this can cause perl to try to parse
those variables as function calls, or other perl constructs (like
matches if you use 'm' or translations if you use 'y'). This is bad
(and is not a problem with the new parser).
In particular, if the student uses 'k' in a formula for which k is not
defined, for example, perl will try to call the k() function.

Add better error reporting in PG translator. In particular, these
changes add two new features:
1) produce a full stack trace when a .pg file dies, and
2) convert (eval nnn) references to filenames, when
possible, in warn and die messages while processing a
.pg file.
There is also a change in the webwork tree that is needed to make this
all work, so be sure to apply updates in both trees.

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.)

Removed warning messages. The macroDirectory and courseScripts directory are now defined from the %envir
variable which is shared directly with the new Safe compartment rather than via calls to $main::macroDirectory
which seemed to be unstable in some instances. I've left the FIXME sign in place just in case there
are still problems.

Zeroed the variable storing the responses to questionnaires. Should
fix the error on questionnaires revealed by the persistance of mod_perl
modules.
Changed warning message in dangerousMacros.pl to more accurately describe
what is wrong when the gif2eps script cannot be executed. (Based on actual
experience running a course on webwork.math.rochester.edu -- I couldn't remember
what my own warning message implied.)

Made changes required to allow caching of these files.
My tests indicate that these changes are compatible with webwork1.8
One possible problem might be the mail-to answer macros
which access the environement variable directly
I think I have this properly patched, but it has not been
tested yet.
