KayleeR's Misc UI Modifications 1.13

- Update to be compatible with patch 1.1.0
- Improve discovery lens to be in line with information that is communicated through fog of war (discovery constructibles on tiles update to be removed even in fog of war).

- Update how the mini map lens checkbox is added to not require replacing the mini-map panel class to avoid conflicts with other mods.
- Update discovery logic to no longer provide information not available to the player (resets fog of war discovery icons on load)
- Add repair category to the production screen.
- Fix base game bug where repairing items doesn't cause the production UI to correctly remove no longer valid repair items.

Fixed some logic on when to remove discoverable icons. Should now only be removed when the now empty tile is visible to you.
