add vec2 qcdebug overloads
no longer silence qt warnings..doesn't seem to be saying anything right now

it used to be some annoying non-us problem though, i remember.
add time nsecs to debug ou tput
use uint64_t for ntime
add assertion for out of range server send large world chunk
add blockAt function...we need to use this instead of all that other

shit. far less error prone, less duplication.
