md task toggler

Add or toggle markdown tasks in current selection.
Works for a single line (where the cursor is positioned) or if text in multiple lines is selected.
If tasks in the selected lines have different states they will be synchronized to the same state.

ā€˜āŒ˜Dā€™ is configured as keyboard shortcut - change this if you want to use a different one
