New Filter for my courses under courses

In order to see only courses within the tab mycourses (site=courses) without lerning ressources we shall add a new filter element (only courses) within the courses related filters. The new filter will be selectable just above the existing filter called "current courses" (see also attached screenshot). 

In addition to that we will add a new column to the listed view where we show the results with "Type" (see here the example with selected courses -> Screenshot)
