another usable release!

v0.2 brings a somewhat important change: app titles.

• App titles are automatically obtained from games on gamecards.
• App titles are prompted for if the target app is on the SD card.
• Emergency dumps of all save data are now stored in sd:/svdt/[title]/[timestamp] if a title is given or obtainable.
• Interactive dumps of all save data are still stored in a new subdirectory of the working directory, but the subdirectory name is now [title]_[timestamp] rather than [timestamp].

Note, however, that emergency save injections still work from sd:/svdt_inject.
