This includes:
- Changing PHPUnit's bootstrap to use https://www...
- Modify all existing expectations to the new wwwroot.
- Amend some tests now with different defaults because of is_https()
- Added a note to main upgrade.php about the change.
- Complete the deprecation information to follow the rules.
- Minor tweak to PLAIN tests to have clearer expectations.
- Completely delete get_global_config() from filters, there
was not much utility keeping it there. Note we have opted
for direct deletion because it's private API, not public one
(and searching github/google/docs did not reveal any use
of those functions either, just in case).
This lets you programmatically prevent certain filters running on
certain content.
Also, I created some unit tests for the basic format_text functionality
since there did not seem to be any yet.
