#333 passed imported LUT names and folder names through tr(), so a LUT
named like a message ("Vivid") was shown translated; they are now shown
as the file names them (builtin_label / new profile_label, as for user
presets). A LUT folder named like a built-in group ("Film") shared that
group's menu widget id and the browser section's open state; both are
keyed apart now. Restores the "Amount 0 = the photo as it was" assertion
#333 replaced, and adds a What's new line.
