[*] NT: Added TTY handle static getter optimization alongside a secret setter API [*] Made ILoopSource virtual [+] Linux: Added console TTY stubs [*] Renamed ConsoleTTY.Linux.cpp -> ConsoleTTY.Unix.cpp [-] Redundant commented out shm_unlink (zero ref condition should unlink, i believe.) [+] Added IProcess async pipe transaction getter stubs [+] Added additional userland env lookup variables: XDG_SESSION_DESKTOP, DESKTOP_SESSION [+] Unix: AuTime::ns2ts
