1. When the user clicked on an incident on the map surrounding incidents were not displayed. Incidents now display when a user clicks on one.
2. When the user clicked on a circle with many incidents on the same location there were only 15 incidents available in the dropdown menu. I fixed the amount and added a conditional. When the number of incidents is less than 60, all incidents are available in the dropdown menu.
3. Increased amount of possible leaves to avoid cutting data displayed on the map
4. Fixed opening Admin Dashboard page in a new tab.
