UPDATE 1.1

- fixed a few bugs/crashes.

- seeds (to grow them put them on sand and pour some water on them).

- save/load function.

- shadows are now a shader, finally giving better performance when enabling them.

- added blending effect, which blends neighboring pixels.

- screenshot button.

- cleanup button which cleans whole "canvas".

- zoom function now zooms whole "canvas" and you can move the camera with arrows.

- particle names display at the top.

- fps are now displayed together (real fps are in brackets).
