v0.5.2

Added

• Double-click a day in the calendar, or right-click it and pick New todo, to add a todo due that day
• Double-click a board column, or right-click it and pick New todo, to add a todo with that column's status and, on a board grouped by project, context or priority, the group's value
• Clicking or right-clicking a calendar day or a board column outlines it, so you can see which one a new todo goes to

Removed

• The zoom slider in Settings → Appearance; the window always shows at 100 %, and zoom_percent in config.toml is ignored
