List of blocks by durability

This is the list of blocks sorted by their "durability" (how much block damage can they take).

This is important in two situations:
 * 1) when mining: more durable blocks are much slower to mine,
 * 2) when building on a planet with hazardous weather (such as Cosmic Blasts, which can deal 12 damage to the area they fall upon) - blocks stronger than 24 hitpoints are very likely to be safe, while weak blocks will be utterly destroyed.

Note: extremely weak blocks (less than 4 hitpoints) are not included.
