Subject: [PATCH] Determine lava and water fluid explosion resistance by their
 block explosion resistance

When selecting which explosion resistance to use for lava and water, vanilla selects the highest value between their block explosion resistance and fluid explosion resistance.

Problems emerge when we want to reduce the explosion resistance of water or lava, since the fluid explosion resistance is hardcoded to return 100.0F and can't be changed by a plugin. This simply makes the fluid explosion resistance the same as the block explosion resistance, which allows plugin to change the value. Since both are the same in vanilla, this has no side effects on servers that do not need to do this.
