Fix terrain brush popup

Closes #729
1. Dark mode now applied correctly (was previously lacking)
2. Fixed terrain brush action (brush active is higher priority than drag, fix tile fetch)
3. Fixed writing of Building/structure labels; apply after Terrain
4. Single terrain brush form allowed, center to Field Editor on launch

Somewhat related: fix Show() load for non-ShowDialog() forms to center to parent.
