Current changes:
1. Compatibility with patch 1.2.4
2. Legend remembers if it was collapsed or not when you enable the lens
3. Positioning changes to lessen overlap with unit UI at some lower resolutions. (Suggest disabling legend for very low resolutions)

Features currently in development (working, but need polish)
- More themes, including colour-blind friendly ones
- Fully customisable colours
- Control all options from legend itself
