Symbols, not timelines; no symbol is special

Browse source 
Everything that holds nodes is a symbol (domain/timeline -> domain/symbol,
:timelines -> :symbols) and a node that places one is :kind :instance. The
reserved :main root is gone: which symbol is on screen is editor state
([:ui :open]), every domain function that needs a symbol is told which, and
a document opens on the longest symbol nothing else places.

Saved projects move to schema 2 through migration 0007, which rewrites leaf
paths, instance kinds and the feature :symbol key; the client refuses a
schema it does not read.
