Added

• Added indent option to pretty printer, which can be used to specify the indentation to use (defaulting to four spaces). This also allows using tab indentation.

Fixed

• Resolve names in PropertyHooks in the NameResolver.
• Include the trailing semicolon inside Stmt\GroupUse nodes, making them consistent with Stmt\Use_ nodes.
• Fixed indentation sometimes becoming negative in formatting-preserving pretty printer, resulting in ValueErrors.
