Renaming the purple color #54
Description
The color purple is not consistent with the basic secondary RGB color names - cyan, magenta and yellow. In the user interface it is called magenta in some languages, but still purple in the rest. The actual color used is closer to purple and in code it's still purple. Part of this is exposed to the users: p must be used in any place that requests a shape code.
For consistency, I propose completing the rename of purple (p) to magenta (m) and changing the color value used throughout the game. Shapez 2 has also switched to using magenta (m). @SkimnerPhi suggested #f066f0 as the replacement color, but I'm open to any other suggestions or objections.
Note: this will affect existing savegames, as the colors may be referenced in map markers, constant signals and the current level shape.
