Added fire!

Select in the block menu

hold mouse to spawn fire(a bit)

while you selected fire, click on the ground or on a block(not gonna work on all blocks,  but on most)

and you will have a normal fire(like camp fire)

you can delete fire ONLY with water, sand and snow.

There are burnable blocks(like wood, ice etc), and when the fire is out, the block will get deleted.

it is not perfect, i cant make it beter(i think)

That's all!
