- Added a "help engine" in the common folder that can be used globally.
- Updated preview and Nutcracker to use the new help engine.
Fix inefficiency with spin and chase effects: don't bother rendering background info if there's not a nonzero background intensity.
Fix the color combining of multiple color intents: actually calculate the alpha properly (in HSV/HSL space).
Refactor the color intent color work slightly, so it's clear if you're getting an alpha affected or opaque color.
Remove some unused code from the preview; looks like it's previously been refactored.
Modification to AlternatingData.cs so that effects previously created prior to changes load with default curve
