add lightweight block propagation ("fluffy blocks")

Browse Source 
Added a new command to the P2P protocol definitions to allow querying for support flags.

Implemented handling of new support flags command in net_node. Changed for_each callback template to include support flags. Updated print_connections command to show peer support flags.

Added p2p constant for signaling fluffy block support.

Added get_pool_transaction function to cryptnote_core.

Added new commands to cryptonote protocol for relaying fluffy blocks.

Implemented handling of fluffy block command in cryptonote protocol.

Enabled fluffy block support in node initial configuration.

Implemented get_testnet function in cryptonote_core.

Made it so that fluffy blocks only run on testnet.
