Shadowed Chat and Player List Text

This implements the (existing but unimplemented) plDynamicTextMap::kFontShadowed flag, making the text of the mini KI (player list and chat) better readable on light and patterned backgrounds.

For best results, an additional Python change is recommended: MOULSCRIPT-ou PR #23.

From H-uru/Plasma#392.
