Shard lighting

[brightrim]

The same lighting was added to shards as with items like the life root, to make their glow actually glow in the dark nights that have returned to Illarion. However the matter of the colour of the light possibly matching the shards and glyphs was brought up.

• Determine whether it is possible to use different colours of light. If there are examples of this already in game, reference them to try and figure out how this works.
• If feasible, add lighting of the glyph and glyph shards colours to each relevant glyph/shard.
