Cat Run devLog Ver 1.8.1

Ver 1.8.1:
1. Added a new Power up to endless mode which turns the game into a flappy bird type control when picked up (green square) and resets back when picking up the reset power up (pink square)
2. added a draft for the Endless mode button.
3. game now follows your score based on:
a. Normal mode - coins, cats saved, distance (score).
b. Endless mode - coins, cats *collected so far*, distance (score).
4. and in order to accommodate the new power up I also change the level layout a tiny bit to give "room to breath" so you wont die too fast when picking those up.

bugs:
1.game might keep going even with 0 cats on screen, press "R" to reset at that point
3.new power up makes you be a bit slower than the back border (as long as u pick up doubles it should be fine), Im still experimenting with this speeds so if u find yourself still losing to the back border catching up to u too fast on 1.8.1 pls let me know :)
