MiliUI Damage Meters

New
- Added a "Grid: ON/OFF" toggle to the top-right corner of the settings window. When it's on, an alignment grid covers the screen while the window is open, so you can line up your meter windows. Hover over the toggle to change the grid spacing. It is off by default.
- Added two choices to Text > Outline: "Monochrome outline" and "Monochrome thick outline". These turn off font smoothing, which suits pixel fonts.

Changes
- Checkboxes in the settings window are now sharper and no longer look blurry on high-resolution screens.
- When you click a toggle or option inside a submenu, the submenu now stays open instead of closing.

Fixes
- Opening the Talents or Spellbook window no longer closes the settings window.
- The close button on the settings window could go dark and stop responding after you moved the window or brought it to the front. It now always works, and you can also close the window during combat.
- Opening the settings windows of two MiliUI addons at once no longer makes them overlap each other.
