minor release

core:

• core config section, allow enabling/disabling modules
• better module detection
• experimental helpers to supply errors with datetime information
• experimental helpers to make it easier to override config, e.g. see https://github.com/karlicoss/dashboard/blob/ff15295d8118494f986ed13757e022ae2aa18000/src/dashboard/data.py#L99-L117 for example usage
• nicer warnings
• initial core.pandas helpers

cli: hpi doctor enhancements

modules:

• big update for instapaper, reddit, ghexport, hypothesis, rescuetime, pocket.
  DEPRECATED: the old way of specifying dependecies either as

  • config parameters (e.g. hypexport = "/path/to/hypexport_on_disk")
  • symlinks in the config (e.g. my/config/repos/hypexport)

  These dependencies are proper PIP packages now, see #79 for the discussion about the change
  This is backwards compatible, but please reinstall them properly as soon as you can (see the updated instructions in the corresponding repos, e.g. https://github.com/karlicoss/instapexport#setting-up)

• provide fake data providers for some modules

• better mypy coverage for some modules
