Support params in queries and transactions

[tonsky]

ruleParams let you write permission rules of type “allow access to anyone with a link”. E.g.

{
  docs: {
    view: "ruleParams.secret in data.ref('docLinks.secret')"
  },
  comments: {
    view: "ruleParams.secret in data.ref('parent.docLinks.secret')"
  }
}

Use in queries:

db.useQuery({docs: {}}, { secret: secret })

and transactions:

db.transact(db.tx.docs[id].ruleParams({ secret: secret }).update({ title: 'eat' }));

Updated APIs:

• db.queryOnce(q, opts?)
• db.subscribeQuery(q, cb, opts?)
• db.useQuery(q, opts?)
• db.tx.ns[id].ruleParams(...).upd...

where opts are { ruleParams: {...}}
