v0.2.5

Home page overhaul.

• Shelves now scroll with hover arrows and carry a More button through to the full grid.
• Jump back in — a shelf of the playlists, albums and artists you actually played recently.
• The play button on playlist and album cards now plays them, and every card gets the same ⋯ menu as a list row.
• The feed pages in more shelves as you ask for them (Show more).
• A time-of-day greeting replaces the static Home header.
• Add-to-playlist works on whole albums, not just single tracks.
• Dropdown menus flip above their trigger instead of running off the bottom of the window.
