The installer writes xsystem35.gr file into the game root directory.
Now save files are created at `files/save` directory, which is outside
the game directory. This scheme is the same as Kichikuou on Web, so it
would make transferring save data between two easier.
Playlist is written to <gamedir>/playlist.txt during installation
("cdrom_device" in .xsys35rc is not used).
Files that match /(\d+)\.(wav|mp3|ogg)$/ are recognized as BGM files
(digits represent a track number). Note that this convention is the same
as Kichikuou on Web.
This adds a minimal launcher activity for the android app, which does
the followings:
- Opens a file chooser to let user select a zip file
- Extracts the zip into the app's internal storage
- Launches the SDL activity
