Fixing a bunch of things:
1. Fox now is afraid of the dog and respects it's space
2. Allowing the fox to move out of the screen when evading from dog
3. Fixing top bar alignment in terms of timer and score (using layout_weight to properly control it)
4. Fixing issue where gameLoop couldn't be set to running = false because it was running it's own thread / class instance (using static flag for running now)
5. Fixing issue with timer double decrementing (misuse of ticker on the activity lifecycle - it was starting the counter twice)
6. Properly finishing the game when ticker is complete
7. Avoid direct calling callback methods for the countdown timer
8. Reducing Fox eating_time
9. Refactoring places where points are added / subtracted and using more substantial numbers (10, 5, etc instead of 1)
10. Added logic to give different points when fox runs away VS fox being caught
11. Removing logic to make the fox evade more than one "position". Now it moves one unit away until the next game loop.
