Add a generic way to render actions in the page content header
and then moved the region main settings menu there for the forum.

* the settings and navigation blocks scss extended .fa which caused
issues with native fontawesome classes like fa-pull-left.

Changing the added class .invisible to .ivisibleblock to avoid hiding the block completely

* Separate the link
* Add style to force color inheritance

Size reduced from 7rem to 5rem for smaller devices
and for courses without a description.

* 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

Using the .text-primary class allows colour to be overridden easily
This will back the dashboard icons look consistent with the messaging icons.

equal size loading placeholders
added list view and summary view placeholders for myoverview

card desks using class .dashboard-card-deck.one-row should not
show a vertical scrollbar

Cards should have a minimum size of 250px wide

target block content only
use same html accross blocks
add one-row class for scrolling cards

Using same card HTMl for recently accessed courses

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.

Only show more than one row of items when the block is displayed in a narrow column.

Fix for boost theme only because of the second block region on the dashboard.

This commit remove an unused template and some custom css that has been added
previously and now is no longer necessary.

Reduce the calculated bottom margin between blocks to half

Increase the fixed width of the column to 360. Already does the realign below centre column

Compiled css file

- remove css for setting a fixed height on course cards
on large devices for block overview
