• [x] Proper logging among bounced nodes
• [x] Refactor / clean-up of the Network service

• [x] Bounce validation on every request whose bounce is defined by the user
• [x] Represent bounces as valid connections [1]
• Solve the implicit bounce issue. Delegated to #379
• [x] Bounce data on bootstrap (inventory?)

TODO:

• [x] Check for cyclic references
• [x] Support customnetwork_id on ServerPublic.connect_to_server/3

Incidental

• Removed NetworkFactory :tada:
• Renamed destination_id to target_id on Tunnel
• Added client_nip to HETypes, as well as to_nip conversion method on ClientUtils
• Added Helix.Client.Renderer system (later on ClientUtils could be moved to Helix.Client)
• Added TunnelFlow
• Added assert_bounce macro helper.
• Redesigned the Loggable API for greater flexibility.
• Logs when player installs virus (with bounce support). Closes #369

[1] - They are, implicitly. AnyMap would call connections_through_node. If server_id is not the Tunnel's gateway_id or target_id, then it always is a bounce. In that case, display connection (link) as bounce from (n-1) to (n+1) of type connection_type.
