Dec v0.7.1

Added

• Proper support for Nullable.
• Bespoke_KeyTypeDict() parameter for Recorder which allows dictionary key fields to be implicitly treated as class tags for their values. This will be removed once I've figured out a more general way to support this.

Fixed

• Type parse cache bug that could cause non-arrays to be incorrectly parsed as arrays.
• Cloning an object with a factory that depends on a non-shared recorded object can, if the stack depth is too deep, result in the non-shared recorded object not yet being ready.
• Decs that are also IRecordable cause errors when referenced in other Decs.
• Security issue: XML documents could cause arbitrary HTTP requests.
