Ethan Centaurai:
    - Attempt at fixing Ticket 112. Drycoded.
    - Added some extra protection for users who have _NPCScan but not _NPCScan.Overlay Fixes ticket #111.
    - Remove leftover debug.
    - Fuck it, remove all support for PlayerPowerBarAlt. It's never worked properly and clashes with other addons. Just use BetterPowerBarAlt if you need to move it.
    - Don't touch the PlayerPowerBarAlt if BetterPowerBarAlt is loaded. This should make nebula169 happy.
    - Add TomTom support to the Expander module. Because I can.
    - Add NPC Scan Overlay support to the Expander module.
    - Very minor typo fix.
    - Changelog override disabled.
