Block protection compat overhaul

- Unifies all block protection checks into helper methods in BlockUtils which trigger all the necessary forge events and vanilla methods
- Implements these checks in all the appropriate places and removes calls to EntityUtils#canDamageBlocks(...) where they are no longer needed
- Changes the mine spell to respect the config settings in line with the rest of the spells
- Fixes earthquake not respecting the settings at all
- Adds a separate config option for dispenser block damage and updates the description for the existing settings to reflect the changes
