Raresight - an Ellesmere Rarescanner/Silver Dragon Bridge

RareSight 1.0

First release under the RareSight name, combining the EllesmereUI integrations
for RareScanner and SilverDragon into one addon.

- Choose RareScanner or SilverDragon from one settings panel.
- Compact alerts with balanced multi-row loot and native click-to-target.
- Alert borders align with the EllesmereUI Quest Tracker at different scales.
- Up/Down tracker movement, loot clearance and combat-deferred layout updates.
- Keeps native scanner queues and controls.
- Warns when obsolete RareScanner_EllesmereUI or SilverDragon_EllesmereUI
  folders remain installed, including disabled copies.

Requires EllesmereUI and either RareScanner or SilverDragon. Both scanners
may be installed; only the selected source uses RareSight integration.
SilverDragon integration also requires EllesmereUI Quest Tracker.

Updating: exit WoW and replace the RareSight folder in Interface/AddOns.
Remove the obsolete bridge folders when prompted; keep the scanner addons.
Use /raresight for settings. Source changes require a reload.
