HistContext addon lists: updated default list and new list for Ireland

I overhauled the default data list. I aimed for short descriptions, worldwide events over country-specific events, and events with clear dates. Some events were removed (Little Ice Age, Smallpox) but most were expanded on.

I tried to include the whole world, although there is a natural bias towards the English-speaking world.

  1. Removed extra spaces
  2. Shortened descriptions: I kept the event, time and place and removed conjecture, e.g. changed “Industrial revolution - child labor” to “Industrial Revolution”.
  3. Replaced entries that had a place in parentheses with a worldwide entry, e.g. “Bubonic Plague of London” replaced with “Black Death”
  4. Removed events with unspecific or general dates, e.g. Little Ice Age, Smallpox
  5. Added many new entries
  6. Updated empty dates

The list is still a work-in-progress and feedback is desirable. I preferred explicit years instead of using “Today” (e.g. War in Ukraine). Most dates are years, but some are ISO dates.
