Update items.lua

Modifies all crafting recipes to use groups instead of fixed items, including adding a new crafting recipe to craft glasses of water using water sources

Special thanks to @mruncreative for showing insterest and inspiring me to do this changes (Resolves #14)

 # claycrafter
-Minetest clay crafter mod. Adds a way to craft clay out of compressed dirt.
+Minetest clay crafter mod. 
+Adds a way for players to obtain clay other than mining, out of a common material: dirt. It adds three new nodes:
 
-Dependencies: 
+**Claycrafter:** Used to convert compressed dirt into clay.
--Default
--Vessels
--Bucket
 
-#####License for Code
+**Compressed dirt:** Just 9 dirt, compressed, useful for saving storage space, too!  
+(Not present if moreblocks is installed, use moreblocks:dirt_compressed instead)
 
-Copyright (C) 2010-2013 Dragonop <joaco-mono@hotmail.com>
+**Glass of water:** Used as fuel for the Claycrafter. Placeable.
