Moved COURSE_TEACHER_COLOR out to style sheets where it belongs (.teacheronly)
Added some efficiency when printing recent activity
- don't print more than one weeks worth of updates
- don't keep re-parsing logs once they've been used
Firstly, I'm replacing all use of old-style global variables like
$HTTY_REFERER with their new-style equivalent $_SERVER["HTTP_REFERER"]
Also using $_POST instead $HTTP_POST_VARS etc
Secondly, if gdversion == 0 (ie GD is not installed) then:
- users are not even allowed to upload new images
- graphs now just print a message instead of failing.
this allows Moodle to still be used even if GD is not present
Moodle tables.
ie user -> userid in many tables, plus in user_students
start -> starttime and end -> endtime
I've just done all this as carefully as I could ... I don't think
I missed anything but it's pretty intensive work and I'd be fooling myself
if I didn't think I'd missed a couple.
Note that this version should pretty much be able to bootstrap itself
using PostgreSQL now ... but this is untested
gmdate to format times, thus allowing it to take advantage of locale, if set,
to print dates in the appropriate language. Several userdate invocations
had to be changed, though, to use the different formatting specs.
