Super Mario Editor Deluxe-Touchscreen Friendly file

Getting ready for a mobile port, so the controls have been simplified. In addition to the item browser, there's now a tile drag bar, a solidity button, and Mario is finally able to become small! Koopa physics have been fixed and a lot of controls related confusion should be gone now. One last detail! Press shift and drag to draw in blocks. It isn't in the in-game instructions!
