Add quest and warning attribute labelTypes

[gcabbage]

Adds two new attribute labelTypes:

• warning - currently yellow - intended to warn the player about things that don't rate a red disadvantage tag. For example incompatible tech types in VotG
• quest - currently purple - intended to mark any items flagged by missions. For example quest items and crafting components.
  • Items with the questItem attribute (e.g. dall sphere, lamplighter prototype) now show an engine tag mission
  • RPG component tag has been updated to use the quest label type

See:

• Military and Illegal tags should be unique colors
• Give incompatible tech types a different display attribute color
• Differentiate baked-in attribute colors

Note - missions that use standard items (e.g. CO2 scrubbers without a questItem tag) will not yet show a mission tag on the item. For these I am planning to implement a system very similar to RPGComponents so the tag will only show while the mission is active
