Library: the Photo Grid label footer is translucent; pt-br for "Color label cleared" (#308)

#308 painted an opaque label-coloured bar over the bottom 24 px of every
labelled photo in Photo Grid, hiding part of the photo, while its docs
said the photo pixels stay as they are. The footer is now translucent
over the photo and the docs say so. Also adds the one string pt-br lacked.

 - Setting or clearing a colour label shows a brief bottom confirmation, like rating a photo; custom label names appear in the message too.
 - On macOS, ratings `0–5`, labels `6–9` and pick/unflag `P/U` now reach the app even when shown in the native menu (issue #283; adapted from PR #261).
 - `Shift+6–9` labels and advances. `Shift+P` picks and advances in Photo Grid and Square Grid; it opens Presets in other views. With Auto Advance on, Shift still moves only once.
