#3 Several bugs(adduser,erasetest,taketest)

[Miguel Angel Gonzalez]

When i select a "subject" in the selector of "view test",
all the test appears. To solve this problem
and see alone the test of the selected subject, modify
the you line 47 and 50 in
the file "erasetest.php".
When an user(moderator or administrator) is "edit ", it
doesn't change the moderator's profile or the
administrator in the bd.
When I add an user one can not write the password
confirmation in the textbox.
If the table" gallowed " this empty one, the users can
take tests in all ways.
The time of duration of the test is uncertain. The
function settype($time, " int ") in it lines her 719, it
doesn't convert the type. Suggestion: to replace for
(int)$time.
Attach patch.
