make camera->pos private to make debugging easier in future
fix script.txt loading from CWD
*nix stacktrace: better detect binary location
pass LOG_LEVEL to stacktrace translator, so watchdog ones are issued as warnings now and not as errors anymore
minor in Matrix44f
fix mapborder drawing on maps with waterplanecolor
access() use consts instead of magic numbers
! up boost requirement to 1.47 and always link boost::chrono
add new SpringTime UnitTest that tests/benchmarks different clock implementations
minor in Matrix44f UnitTest
TimeProfiler: use spring_time instead of SDL
spring_time: always use a class and use [boost|std]::chrono instead of SDL
* ~same time costs (check the SpringTime UnitTest)
* ~100 _nanosec_ precision instead of 1 millisec (that's a 10^4 difference)! this should help to better share simframes across time and allows us to use SCOPED_TIMER with very small functions (Matrix multiplications, ::InView, ...)
* use int64 for time vars, costs nothing compared to int32 (tested!)
fix minor in validation's run.sh
limit Lua memusage to 256MB (untested!)
*I _hope_ Lua runs GC when we return NULL there*
