MDL-47614 gradereport: Apply a background colour

background.
MDL-47189 my: Fix the addition of default blocks to my/ page

Fixing the upgrade script so that they attach the new blocks
to the right my_pages entry. An upgrade script has also been
added to fix the existing bad data.
MDL-47189 my: Update test to check that existing blocks remain after add

passed when looking for the string anywhere.
MDL-47649 csvlib: must not leave files open

I added a destructor to csv_import_reader ensure the file is closed.

I also ensured that the gradeimport_csv unit tests did not hold onto a
reference to the csv_import_reader object while the phpunit framework
tries to tidy up moodledata.

Finally, to stop CiBoT complaining, I fixed up the PHP4-style
declarations in the CSV import class.
