Did some layout changes to home view. Implemented help-pop up and list of active milestones. Did also make the page more similar to other pages.

Needed to change the method since get all milestones implemented pageable. This should later be another method to get all milestones for this exact purpose.

Implemented pagination to active milestones. Did also make the component more uniform to other similar components.

Created a component for the list of active challenges. This making the challenge view more simple and component based.

Added method to delete an active challenge. Did also change the layout in case of long descriptions. Therefor enabling scroll when hovering and overflow.
