Update for Nim 1.0.0

* `--yesterday` is like `--today`, but for yesterday 😄.
* `--or` changes the behavior of filter criteria to return a union of
  events matching an of the criteria than an intersection of events
  matching all the criteria. Example:

      ptk list --today --yesterday

  Will never return results (because the criteria are mutually
  exclusive).

      ptk list --today --or --yesterday

  Will return the marks for both today and yesterday.
