Add back statically-set reserved IDs for air blocks only, make it clear they're "reserved" (#1502)

Browse Source 
* Add back statically-set reserved IDs for air blocks only, make it clear they're "reserved"
Also:
 - Ensure that reserved is never returned in GET block operations
 - "empty" thus doesn't exist in the GET update methods; remove the needless checks
 - Allow GET/SET chunks to determine their own default values for non-present blocks/sections

* Add comments
