Give the keyword sheet's field focus, and the empty trash its own words

Without focus the keys typed into the keywords sheet went to the grid
behind the scrim, and the Return meant for the keyword opened a
photograph. The naming sheet already takes focus on open; do the same.

An empty trash said "No images found — check the library folder and which
formats are ticked", which sends someone off to fix a library that is
fine.
