Test release

It should make web browser to open in fullscreen mode. Please post /data/web-browser-fullscreen.ini file in Issues.

It would restore back after rebooting or changing the system language. Or run the restore.elf without rebooting.

I tested on FW 4.03, 12.20 and 13.60 and they works without kernel panics.
Thanks to the community provided fixed support for FW 10.01, 7.00 and 7.61 from Discord by SHARKS and Fubc.
Thanks to @Sanya87532 for contributing fixed support for FW 12.02 and @freefelt for FW 11.20.

Take your own risks to test them!
