Bug fixes

Added

• __eq__ methods on Block and Transaction
• Test vectors

Fixed

• Parsing of 00 as a 1-byte push operation
• Parsing of invalid push operations
• TxIn.from_json method now properly instantiates CoinBaseScriptSig where appropriate
• Generic Scripts unhexlify method now works as expected (i.e. no identification is performed on the unhexlifying of Scripts, ScriptPubKeys and ScriptSigs)

Backward compatibility

• Should not break past usage, apart from usage that for some reason relied on the bugs that are now fixed
