minor bugfixes and refactoring
- Blockchain should store if it's running on testnet or not - moved loading compiled-in block hashes to its own function for clarity - on handle_get_objects, should now correctly return false if a block's transactions are missing - replace instances of BOOST_FOREACH with C++11 for loops in Blockchain.
