[cleanup] the revenge of Mr Proper
[fix/evol] work on better Interface/Task/Conversation/… sync and bot stop action in order to avoid races and locks
[debug] log more when connecting to peer
[evol] Cyborg/Interface: support returning API call replies asynchronously
[licence] updated copyright years
[fix] recreate the whole API interface tree, root included, to ensure no clash is possible during concurrent calls
[evol] BotnetTask DSL: now that we have one Task per task, close conversation thread as soon as the task is finished
[fix] separate core api version from cyborg service api version
[evol] server API tree reworked using a DSL (reply handling rework is WIP)
[layout] reorganization
[evol] connect_peer: made most of the code generic to all backends
[evol] connect_peer: do not open multiple connections to the same peer while one is being attempted already
[fix] remove traces of old Botnet DSL
[evol] Task-based client DSL §4 (many fixes, helper, bot stop condition, more logging)
[evol] created a DSL for client-side calls (several conditions (calls only at the moment) can be joined together in order to exploit parallel tasks via asynchronous calls)
[fix] ensure pending threads/conversations are uniquely registered
[evol] add system/user notif to bot level and detecte when a conversation is idle, to close it after used in connect_peer() with block
[fix] ensure ask_to_stop() waits gracefully for conversations to finish while stop() just stopp at once
[fix/evol] conversation/bot protocol rework §8 (refs #30)
[fix] BotNet: handle UNIX Socket connect failure (EM.connect fails at once, not via the handler)
[evol] add client support to BotNet
[evol] unified BotNet interface for both client and servers (as a client is also a micro server)
