This patch allows the much requested selection of individual instances of modules within a course to backup and restore.
It needs A LOT of testing and probably some prettyifying too.
Complete refactoring of the system that was really awful (my fault!).
Now everything is in its place and working like a charm, making things really
easier to be implemented and amplied. Bug 3678

Note: Everything is merged from stable but the quiz module because it has
other changes not merged for now. I've skyped a message to Gustav about it.
Merged from MOODLE_15_STABLE
It wasn' working fine because the wiki_pages table hadn't an id (primary key) field.
I've created, in the upgrade process, a temporary table to copy all the wiki_pages
records and then, drop and create again the table.
Tested under MySQL. Need to be tested (both creation and upgrade) under PostgreSQL!!!
Minor modifications to ewikimoodlelib.php to work with this new id field too. Seems to work
although deeper tests will be welcome (attachements, binary contents...)
Cross your fingers! ;-)
I've left out stuff that didn't seem necessary ... including a lot
of the Wiki plugins which were quote large... I'm not sure if this
is currently working ... I'm about to try it out.
