Regex is great

GetBlockInfo\(this, \((\w+) (\w+)\) ?=> ?\2(.+)\);
GetBlockInfo<$1>(this)$3;

SetBlockInfo\(this, \(ref (\w+) (\w+), \w+ (\w+)\) ?=> \2(.*) = \3,\s*value\);
GetBlockInfo<$1>(this)$4 = value;

Newly created blocks use the initializer to set properties, allowing the user to set per-block properties

Removed BlockIdentifiers.OWNED_BLOCKS as the original got replaced with an array
Added the correct group for each supported functional block
Removed EntityFactory property from IEntitySerializer as it is provided on deserialization

They are useful
