- Made the SQL ping interval default to 7 hours.

- Memorize cast time now can't be reduced by status changes neither.
- Made skill_unitsetting remove the group when no unit-cells were placed down. basicly this means that if landprotector blocks all tiles, the group will be removed from memory, preventing said group from counting to the total number of skills you can set.
