fix: CSPRNG on Windows, and a window's first title is the package's app name

Browse source 
Crypto.random_* and Uuid.* read /dev/urandom, which Windows lacks, so every
byte was zero; the Windows target now calls RtlGenRandom (advapi32).
ludicc takes --title, which ludic build/run/bundle pass from package.ludic's
app name, so rt_init opens the window under that name instead of the
program name.
