Checkbox inconsistent behaviour

[Chaosmeister]

If a line starts with [ ]/[x], a checkbox element will be created by the markdown parser.
This also works if the line starts with a bullet point list indicator +/-/ *, quotes and their combinations.

If there is text in front of the [ ]/[x] the markdown parser does not create the checkbox

the checkbox parser does not distinguish this case, yet.
this checkbox now incorrectly offsets all "correct" checkboxes

[Chaosmeister]

we can either allow checkboxes anywhere in the text in the markdownparser or adjust the toggle algorithm to only include valid markdown checkboxes
