Test build: trophies with an encrypted npbind.dat (#22)

Test build for #22. Not a release: the launcher does not offer it as an update. It is 0.51-linux.15 plus a fix for the Trophies page, waiting for testing.

Trophies with an encrypted npbind.dat (#22). Some dumps have sce_sys/npbind.dat left encrypted, so the game's trophy ID (NPWR05818_00) could not be read from it and the Trophies page said the file was missing. For Bloodborne, the launcher now uses the game's own trophy ID when the file doesn't have it. Without the trophy key you get the icons and PSN's English list.

If sce_sys/trophy/trophy00.trp is encrypted or damaged too, the Trophies page now says so, instead of reporting a wrong trophy key.

What would help: open the Trophies page and tell us what it shows, and whether the trophy notice appears in the game when you earn one.
