MDL-36162 core_message: removed the unnecessary and confusing course URL parameter as well as fixing the broken breadcrumb
MDL-36025 qtype calculated: Fix handling of "-0"
MDL-36640 Logging: Correct testing of log->info.

log->info sometimes contains additional information which can be looked up
from other tables. This should only be attempted if the field is numeric,
but the CSV, XLS, and ODS outputs were not making this check.

There is an additional case for the print_mnet_log function which has not
been covered - this is because the mnet logging is currently broken beyond
the scope of this bug rendering this section untestable. These issues are
raised in MDL-36642.
MDL-33125: core_backup: Prevent import/activity duplication from duplicating manual grade items
MDL-27619: Prevent teachers from turning course Outcomes into site-wide ones

Similar to the issue which allowed teachers to create site-wide scales by editing a course-specific scale (MDL-24682), teachers could also promote a course-specific scale to a site-wide (standard) by editing it.  As with MDL-24682, removing the course ID check (leaving just the capability check) prevents this unauthorised creation of site-wide (standard) outcomes.
MDL-36601 Ensure that reports remember all days setting

All Days was set as the nothing value, but this nothing value was used.
Additionally, an insufficient comparison meant that the selecteddate then
became Today.

The various review options should be independent.
MDL-36742 question bank: get rid of flicker during page load.

MDL-36845 excel export: don't output invalid sheet names.

We should clean any proposed worksheet name, to remove the characters
that Excel does not allow.
MDL-36897 quiz: redirect teachers from summary to review page.

There is already logic like this at the top of attempt.php. If the
teacher arrives at one of these pages for a student's attempt, for
example by clicking a link in the logs, then they should be redirected
to the review page to see the students attempt in its current state.
MDL-36942 xml question import: don't add spaces.

They are not necessary anyway, there is a \n character at the end of
each line.

Thanks to Richard Lobb for fining the problem and how to fix it.
MDL-36954 question bank: stop centring question name.

This was a regression caused by MDL-21625. These CSS changes
put the display back to how it was, while leaving the table
cell as a TD  for accessibility.
