suggestion of mikade's - delete old mines if the collision array shows signs of filling up. This is kind of an edge case, esp now that array is up to 1024, but should prevent (easiest) way to crash by collision array overflow (endless mines/minestrikes).

bump up max collision to 1024 entries

Tiny bit of progress on download page - hooked it up to "Info" button for now.
