[evol] Protocol/Interface: don't check for existence before node call, it is already done in call and a loss of time

[evol] API: implemented hidden nodes and used it to create a '?' node used to search children based on their attributes
[fix] Protocol: check node existence asynchronously for CALL

[evol] allow splitting the API interface declaration over multiple files/directories, split MapMaker interface, and added cross-nodes storage during the interface life (as we can't use closures across files)
[evol] BotnetTask DSL: now that we have one Task per task, close conversation thread as soon as the task is finished
[fix] mistakes in API Interface: forgot to export node_name, and forgot :inspect is not available for nodes
[evol] server API tree reworked using a DSL (reply handling rework is WIP)
