Added additional pagination options based on the amount of courses the user is enrolled in.
This will allow the user to display all courses on one page if they wish, and scale based on their total
courses up to pages of 96 courses, now defaults to `All` if they have less than 12 courses and hides the
dropdown menu as there is only one choice.
Added an admin setting which allows the administrator to set the available layouts for users and which
defaults to all layouts being available, or the card layout only if no layouts are enabled.
If only one layout is enabled, the dropdown `nav-display-selector` template will not be displayed as
it can no longer be utilised.
If the user preference is set to a layout that is no longer available, this is ignored and the first
available layout defaulted to.
Added an administrator setting to set the visibility of the course category for the my overview
block on the users dashboard to support usage scenarios where displaying the course categories will
clutter course overviews.
