core_course_get_contents was only checking for modules visible by the
user (via uservisible).
It was not checking for modules that are not visible for the user but
should be displayed in the course because they have access restrictions
configured.
Right now this WS is returning all the sections without advising if is
a stealth section or not, this have some implications (in the mobile
app right now the stealth sections are displayed)
- New site setting to define the default course duration (used to set
the default end date for some course formats)
- End date setting out of restore
- Fix tool_uploadcourse
- Other fixes here and there
This commit reduces boilerplate code.
It also forces WS returning files to always return the following
fields: filename, filepath, mimetype, filesize, timemodified and
fileurl.
