Up to [LON-CAPA] / loncom / interface

First, added unescaping of $key in lond dump command.
Next, I added a new way to download student course data.  There are now
two functions for storing data, DownloadStudentCourseData and
DownloadStudentCourseDataSeparate.  These two functions base their running
on input parameters.  The option parameters are whether or not to check
the date for downloading, whether or not to store all the dumped data or
extract out the data you want, whether or not to display a status window.
The extracting data parameter will be best utilized if someone adds in the
ability to send a list of what parameters are desired and perhaps some simple
commands to affect how that data is processed, like tries, sum would
sum record the sum of all the tries for a student.  This is just an idea.

Currently, I have all the statistics modules using the extract ability.
This slightly increases in download time, but drastically reduces cache
size.  Possible ideas include pushing the extract to the lond side with a
list of parameter/commands, or even downloading everything to a temp cache,
then extract the necessary data into the cache then removing the temp
cache.  There are lots of other possibilities, which can change the download
time, cache size, and other factors.  Now, only loncoursedata handles the
downloading of data to a hash.

lonstudentassessment was changed slightly to remove ' ' as a link if the
student actually hadn't attempted the problem.

lonproblemanalysis was updated for the new str2hash type functions.  There
are a couple of (cludges/fixes) for it.  Depending on whether or not the
str2hash type functions are changed, these may or may not need to be
updated.

lonproblemstatistics was drastically overhauled.  Most of the processing
was removed.  Now, it just does its few statistics functions and outputs
the table.  Currently, I broke the graph, discussion column, and
discriminant factor columns.  These will be fixed on the next commit soon.
There is also no caching done.  This will also be remedied soon.  The
problem that will need attention with caching is to know when to update
the statistics cached data when a student's course data is updated.

Lastly, I plan to add perhaps a toggle legend display button, another graph
button(percentage correct), a button to send the CSV format(not just display),
and add a toggle button for sorting within a sequence and sorting all
the problems.

Also, I changed the look and feel to be the same as the class list page.
Also, the displaying of sequence headers and child sequences are not
working.  This will be fixed, but thought will be put into how best to
make it look and have a similiar fill for all the table combinations.
