Added flowers to the game:

• Rose, Marigold, Sunflower, Cornflower, and Violets now appear in new worlds
• Mining the flowers will give you multiple new seeds, and the petals will mine into petal pixels that drift slowly down when dropped, similar to snow :)

Also, I fixed the issue with animals spawning inside of machines - now they do a 50 unit check in four directions to see if there are any constructed pixels before spawning, so this seems to be a lot better!

Now that the flowers are in, we have the basis for adding paint and the paintbrush tool in a future update, so look forward to that!
