The excel 5 writer files were using OLE licensing which is GPL incompatible.
These classes are not used in core.

Also commented in mod/quiz/upgrade.txt to inform developers.

The main changes here are that the "select the text in" step was modified to select only the

Some tests had to be modified to match the new behaviour, and another "real" bug was found in the table plugin.
