tests/basic-joins.js: dependencies was uncommented and fixed ($gt --> $gte)
smart-publish.js: publishCursor() now takes cursor as its first argument instead of taking it from globals
deepCopy function was added (JSON.parse+stringify), now all fields passed to smart*() are deep copied to avoid headache
mergedData property is now available for collection item together with 'data' and 'count' - it's actual copy of data published to client
Version version of updateChildren() and dependencies tracking was added
tests/basic-joins: added three more tests (enable 4..10, disable 1..7, disable 4..10); disabling do not work yet
