Moodle 32 - Global Search issue with Database Schema (#248)

* Fixes #243 - Adds the fields 'intro' and 'introformat' in the attendance table.

This is done according to https://docs.moodle.org/dev/Activity_modules#install.xml

* Added 'intro' field. If not empty it will add a header (title + intro) in the view page and will be displayed in manage and report pages.
