Add Course Alerts Page

[Jeremy Hopkins]

PR 21 provides code for adding a banner to a course if it is hidden.

I know from experience this is a very useful feature and would like to integrate this.

Beyond simply warning if the page is hidden I would add options to prompt for course image and course summary to be completed, particularly in Adaptable where the front page of the site relies on course summary images to render the tiles.

So, in addition to the settings provided in PR 21 I would add additional settings so that alerts are displayed (optionally) if:

1. course is hidden
2. there is no course summary
3. there is no course image

The following strings will need checking in ca / es language packs, I am adding them using Google translate.

• $string['alertsettingscourse']
• $string['alerttypedisabled'];
• $string['alerttypedisabledesc'];
• $string['alerthiddencourse']
• $string['alerthiddencoursedesc']*
• $string['alerthiddencoursetext-1']
• $string['alerthiddencoursetext-2']

Partially Fix #570 Adding alert if course is hidden into course page

→ <<cset 44ee725ee1af>>

Check for hidden course has been added, opening as checks for summary are not present yet, these require capability check.

Also there is bug on the dismis feature of these alerts.

Also replicate this feature within same renderer:
