Add nomedia flags to PPSSPP Homebrew Store titles

[Jaffacakelover]

What should happen

When a game is installed from the PPSSPP Homebrew Store, several of the titles add their images into the Android Gallery. A minor annoyance; could this be fixed by adding a .nomedia file into the pack's image directories?

Yes, this we should absolutely do. Though, .nomedia are recursive, or at least should be. So putting one in /PSP/GAME might be enough?

[Jaffacakelover]

Yes, that would catch everything except PPSSPP.dl.

I've also done a quick check, and I'm glad that texture dumping doesn't add hundreds of files to the Gallery!

[hrydgard]

Oh, the download temp file? That one shouldn't be much of an issue, should it?

yeah i had to create .nomedia file on android to prevent texture pack flooded my gallery

I'm gonna make it auto-create one inside the PSP directory directly. I don't think you ever want media scanners anywhere in there...

[hrydgard]

Unknown made a good point that users might want the screenshots directory to show up. So I've simply made sure we create .nomedia files in a few more directories instead in an upcoming PR.

If someone is missing screenshots in their gallery, just delete /PSP/.nomedia.
