Disco! 3.5.0

A polish pass over the whole interface: clearer text, less wasted space, and a round of fixes.

Nothing playing? Start something

When no song is loaded, every theme now shows how much music is on the card and two ways in, where the transport
buttons would be:

"28,619 songs on the card" under Nothing playing.
Shuffle all plays the whole library in random order; Browse opens the Library.

Zune keeps its text links; Null says it in its own short form.

Same typefaces and colours, larger sizes and less empty space:

Music: title, artist and album sit midway between the clock and the progress line; the times are larger.
Equalizer, Date & Time: the controls fill the page; larger names, buttons and rollers.
Headers: long titles (Equalizer, Playlists) keep a large face; Apps and Weather match the other headers.
Lists: Settings rows, the Queue's buttons, empty Library lists, Up Next and search results use larger text.
Battery, Weather, Stats, Volume, Song Info and the colour picker: small captions one or two sizes up.

Now Playing: larger title, artist, album and times; larger previous / play / next. Text keeps clear of the
seek ring.
File info line is compact and always fits: FLAC / 1411kbps / 44.1kHz.
Quick Settings: larger state lines ("on", "low") and "brightness".
Keyboard (Search, passwords, renaming): larger, evenly spaced buttons and larger typed text.

The progress no longer breaks on songs longer than 35 minutes.
The clock follows your 12 / 24-hour setting.
Previous / next are readable in light themes.
It closes when the screen behind it changes, and touches on it no longer reach the screen underneath.
It redraws only when something changes, and not at all while the screen is off.

Screen Off now works with Screensaver Off. The screen turns off after the Screen Off time since the last
touch. Before, it never turned off in that combination. If you had Screensaver Off to keep the screen lit, set
Screen Off to Off as well.
Back on Home goes nowhere. Reaching Home by any route clears the Back history, so a back swipe no longer
reopens the screen you left.
Passwords: the Wi-Fi password field has a show / hide button in every theme (Zune had it already).
The Library's "Hold an item for more" hint appears only on lists that have items.

Quick Settings: Rescan and Wi-Fi updated the wrong button when moved from their default places.
Curved lists: a long title (Library management) no longer runs under the arrow at its right.
Ring: text on accent-coloured buttons (Equalizer On, Date & Time Set) is readable.
Song Info: "Sample Rate" stays on one line. Colour picker: the two chips fit their text.
Null: Equalizer band labels no longer run together; the battery graph shows "24 h ago" in full.
Zune: the date's next clears the bezel; an Equalizer row no longer sits under edit / rename; the Bluetooth
and Wi-Fi lists end above the scan link; the nothing-playing screen no longer shows a stray "/".
Braun 2.0: Date & Time sits below its header. Braun: the screensaver's weather tag shows the temperature.
Disco: Working mode icons no longer touch their labels.

Binary record: RELEASE_3.5.0.md. Update from the SD card as usual
(guide); no reflash.
