Passing the last message (which can virtually contain any character) as
a parameter for the {{#str}} mustache helper can break the JSON parsing
which eventually leads to the breakage of the messaging UI.
So for simplicity, revert the addition of the 'conversationlastmessage'
language string and render the sender and the last message as separate
elements.
* all dashboard card templates moved to /course/templates/
* added aria labels for course short name
* removed ":" from other course aria strings to improve screenreader output
Significant string changes:
* courseoverviewfiles, courseoverviewfiles_help, courseoverviewfilesext
in core, configcourseoverviewfilesext, configcourseoverviewfileslimit
in core_admin, areacourseoverviewfiles in core_repository - renaming
of 'Course summary files' to 'Course image'
* Add clarification to delete messages lang strings
* Stop message polling when sending a message to fix UI bug
* Publish update last message event when polling finds more messages
* Remove logged in user from group conversation participants list
* Use user object to fetch user preferences to reduce DB calls
* Remove animated slide transitions because the browser breaks when
showing some conversations

users.
This chagne adds support for a new feature known as Context Locking.
This allows a context to be locked, thereby removing all write
capabilities for all users (including admin) for that context, and all
child contexts.
Create a conversation instead of throwing an exception to get the
behaviour working as it was before.
The string lang 'conversationdoesntexist' can be removed because
it was added in MDL-63466 and it's not used anywhere more.
Change the star icon from being in a button and allow it to be
inline using spans instead of divs.
Add the option to passes css classed to the template.
Significant string changes:

as the option no longer exists
* considereddigitalminor and digitalminor_desc, core - more
child-friendly wording
* configmessagingallusers, core_admin - clearer explanation
* auth_dbtype, auth_db - fixed broken link
