FliperOS 0.8.1

The first ISO with the update system: 0.8's build stopped at the audit before publishing, so 0.8.1 brings everything in 0.8 (in CHANGELOG.md) and comes with updates 1 to 7 already applied. An installed 0.8 gets the same changes through the updates at boot.

System changes:

• New boot splash: an animated text theme in the style of modern terminals is the default
• More splash themes come in the image (Cogwheel, Into It and Windoze 95), and ~/splashscreen is the folder for your own themes
• New default LXDE wallpaper
• The update check at boot waits for Wi-Fi to connect (on Wi-Fi it gave up before the network was up)

Package changes:

• OpenBOR: paks made for OpenBOR 3.0, which OpenBOR 4 refuses, open again. OpenBOR 3.0 (build 6391) comes in the image, and when OpenBOR 4 fails on a pak the launcher remembers it and opens that pak with 3.0, with the same button mapping
• Attract-Mode Plus: the Basic layout is the default, sharp on the CRT, and every display without filters gets GroovyArcade's: All Games, Most Played, and by genre, manufacturer and year

fliperos-setup changes:

• New: Setup > Splash screen, to choose the boot theme, with a preview
• The menu no longer freezes after a splash preview

Tool changes:

• ISO build: updates/ goes into the build's Docker image, so the ISO records the level of the last update (0.8's ISO came out with level 0 and failed the audit)
• tools/build-openbor-legacy.sh: builds the OpenBOR 3.0 that comes in the image
• tools/vm-test.py: the dev and site runs record the update level after the rootfs

Documentation:

• Step-by-step guide from writing the USB stick to playing a game, in the README in English and in Portuguese (README.pt-BR.md); the Portuguese website links to the Portuguese README
