=======================================
WARNING: DEV IS CURRENTLY VERY UNSTABLE.
This is a mega-checkin of the new Roles system. A lot of changes have
been made in core and modules.
Currently there are a lot of rough edges and known problems. We are
working hard on these .. .the reason for getting this into HEAD at this
stage is enable us to move faster (our branch was diverging from HEAD
too much).
Please keep an eye on http://docs.moodle.org/en/Roles for current status
and information for developers on how to use the new Roles system.
Added default values to migrate2utf8.xml, for any varchar and text field types, if the default values for these fields were not defined as '' in the MySQL table creation script.

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
Basically all the Database functions are in lib/datalib.php
and the web functions are all in lib/weblib.php, so
moodlelib.php is much thinner than it was.
Data functions have been extended ... most old calls will
still work, but now many more SQL commands can be performed
using the datalib functions rather than using SQL. I'm
currently moving through the whole tree replacing SQL
calls or at least concentrating them in one section of
mod/xxx/lib.php
Still working on forums, quizzes, surveys, resources.
The tree is currently not full working ... some things are
half-completed ... will resume tomorrow.
