MiliUI Cooldown Manager

New
- Bar-style elements can now have an edge shadow, matching the icon shadow that icons already had. This covers class resource bars (both solid and segmented), custom segments, custom bars, proc decks, the Cast Bar, the Focus Cast Bar, the Skyriding bar, Buff Bars, and custom groups set to bar layout.
- Three settings control it: Shadow (off by default), Shadow size (1 to 8 px, default 3), and Shadow opacity (default 60%). Find them under Resource Bars (global and per-resource appearance), Cast Bar, Focus Cast Bar, and in each bar page's layout section when using bar layout. The shadow is drawn outside the border and does not change the bar's size. Blizzard style bars have no shadow.
