This is essentially just a simple recipe idea, though it would be cool to change the behavior of beds too. The main idea behind this is to make beds harder to obtain. It'd be great if this was made for 1.6.4 - I'd love to have this on my private modpack.
New Items
Block of Wool - made by nine wool, this will make for a sturdier bed (might include other colors than just white).
Sturdy Plank - made by nine blocks of wood (might include support for mods such as natura, Bioms O' Plenty, and Forestry along with other vanilla trees).
Sturdy Bed - crafted by two rows with blocks of wool on top of sturdy planks.
Behavior Changes
Vanilla Bed - Is changed to a durable state, can only be used a few times. The more it is used, the more unreliable it becomes. On the last few uses it will teleport you a distance away from your base.
Sturdy Bed - This bed has infinite uses and will be able to withstand explosions.
