Vastly improved styles, lots of inline styles removed, markup improved.

Updating index page with all the latest from blocklib and pagelib.

Change the semantics of blocks_print_adminblock() to make life easier to
developers who use pages. Conversely simplified the code a bit in courses.

Dropping the use of MOODLE_PAGE_COURSE <gasp>!

The new constant is PAGE_COURSE_VIEW, and it's more streamlined with the
new CSS-related ids for 1.5. There are great possibilities for the future
here, so we 're getting ready.

On the other hand, this has to be the ugliest hack I 've ever inflicted
on any program (look at pagelib.php). Thankfully it will only stay for just
a little while.

Fixed incorrect use of optional_param.

Fixed the double-header bug when configuring a block in the front page,
as reported in bug #2440. Credits to Dan Marsden for the report and the fix.

_ added the ids for the layout table with the 3 cells

Fix for bug 2241:

I hope this time I got everything changed to the new Page interface! I 'm
really sorry for messing up and breaking new installations... :(

Also moved the only two functions of the API outside the page_base class.

Somehow I forgot to commit these and the whole page setup wasn't working
after renaming MoodlePage => page_base.

NEW: The code now supports dynamically plugging your own Pages and block position
identifiers into Moodle without messing with the main libraries at all.

UPDATE: Many functions in blocklib now use pass-by-reference for speed.

UPDATE: Class MoodlePage has been made more presentable and robust.

MAJOR CHANGES:
--------------

Brand-new pagelib.php at your disposal! It slices, it dices, it makes your coffee.
It still doesn't understand women... Read the comments in pagelib.php for a first
impression. Feedback highly encouraged!

Blocks code has undergone significant changes to work with Pages. Flexibility is its
middle name, since I think (without having tried it) that adding e.g. a third
placeholder for "center" blocks in courses, with full support for moving around etc,
will now take about 15 lines of new or edited code. If you are not impressed yet, I
suggest watching a documentary on solar physics. :P

MINOR CHANGES:
--------------

Added instance_allow_config() in the blocks class hierarchy to supplement per-instance
configuration options. You can override it to return true and thus get configuration
amenities without allowing multiple instances.

Minor polishing to comments and documentation (whatever caught my eye was game).

Tightened up some code here and there by utilizing all the new features.

BUGFIXES:
---------

A bug in restore_execute.html caused hidden blocks to not be restored at all.

Code based on the work of Daryl Hawes for the blog module. Thanks, Daryl!

Please test the hell out of it as it's sure to have issues that need to be
ironed out.

after removing empty line at top of section the editing icon was now a bit cramped in, so added an empty line below it but only if editing is on.

Changed the way applicable formats for blocks are handled. The changes are
short codewise, but to grasp all the implications read the forum discussion
at the relevant URL.

It's rough but it works.  I will be doing lots of work on making it
slicker so don't translate the strings just yet.

site front page can now have a topic section, see http://moodle.org/mod/forum/discuss.php?d=9444#45748

so we have more information.

   $CFG->loginhttps

After logging in via https, Moodle returns to a normal http URL

Now the site has blocks by default. Also, block panel width is restricted even
if there are no blocks to display.

is now "Course categories" rather than "Available courses"

since inheritance doesn't seem to work
