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.
