Jaffas and more!

- improved little spiders to produce special kinds of cobwebs like ender, redstone, glowstone, limsew dropping piles - those combined create final product
- added tool to mine obsidian (and sky stone from AE2) - *Pointed Pick*, also hits hard creepers and endermen, chance on spawning enderman when killing zombie or creeper
- added switchgrass charcoal
- added support for special cobwebs into cobweb harvester
- removed cobweb search cost from cobweb harvester, increased speed and internal power buffer
- added custom little spiders' eggs, replacement for spawner eggs (when entity ID changed those spawner eggs got broken)
- added spider "happiness" affecting rate of cobweb production (better results in dark, not crowded areas)
- spiders are spawning eggs - similar to chickens and ducks
- increased dust gain from mallet recipe (jaffarrol ore -> 2x dust)
- slightly boosted jaffarrol tools to match tools from other mods - jaffarrol tools were more expensive, yet worse
