BIG CHANGE: fanculo avevo scritto un poema non ho voglia di riscriverlo.

Browse source 
TLDR: updated bindings, "virtual" classes now do less, and only deal with
managing the persistence of the codemp object within the editor.
the actual commands do the interaction with codemp.

moved away from asyncio, now its callbacks spawned on the async sublime thread.

the client now is much more central and knows everything.

split the join command into join workspace and join buffer, as it was before.
simpler and better ux.
