Refactor events.list.

Browse Source 
The SQL has been simplified and the following changes made:

- The `sequence` argument now can only take one individual
  sequence, not a list of sequences.
- A new `sequences` argument is recognised. It takes a list
  of sequences (as a string).
- A new `label` argument is recognised. It takes a label
  name and returns events containing that label.
- A new `jpq` argument is recognised. It takes a JSONPath
  string which is applied to `meta` with jsonb_path_exists(),
  returning any events for which the JSON path expression
  matches.
