Note: On purpose, the course format social wrong version (2015102100)

current 2.8rc1 (2014110400)

Fix all the things, including:
* Fix $PAGE->url
* Fix coding style.
* Add event for reportviewed
* Removed broken callback  gradereport_singleview_profilereport
* Removed vertical-align-middle
* Changed prefixes in css
* phpcs fixes
* moodlecheck fixes including phpdocs
* Move classes to use autoloading
* Remove all smelly code tricks like func_get_args, scandir etc (lots).

Added pagination back in with some general fixes.

Renamed to Single View in MDL-47289.

Revert "MDL-30843 and MDL-30842 - accessibility compliance: Add <label> for form input text and select tag"

This reverts commit f9f281b8.

The permissions are now going to be verified as part of the weekly release process.

MDL-20700 coding style cleanup - cvs keywords removed, closign php tag removed, trailing whitespace cleanup

MDL-16493 file and picture element migrated; waiting for file picker to mature, presets not finished yet

to do with how the field classes worked.  Now it should be even easier
for developers.

No changes for users.  :-P

The changes are not well tested yet!

Finally, we have an early version good enough for everyone to
start banging on to help us polish it up and find bugs.

Please take a look and file bugs in the bug tracker under "Database module".

We urgently need
    - new icons for existing field types
    - testing on PostgreSQL install


Coming soon (?):

    - Many more field types:  calculation, checkbox, relation, date, datetime,
                              time, email, group, list, user, number, richtext
      (Please let us know if you are interested in developing any of these)

    - A way to save and restore "presets", which are field/template sets

    - Backup/Restore support

    - Groups Support

    - RSS support

Many thanks to Yu for all the hard work under my whip.
