workaround for reversed separating normal in gjk/epa when using very small shapes, detect case and revert normal.
use smaller world size (10 units versus 100) for higher resolution shadow map
use a hard-coded rolling friction of 0.2 for objects in physics server (will make this configurable)

another step closer to useable shared memory C API
...
(force/torque sensor needs new API)
in a nutshell, users of shared memory physics API should not
directly poke into shared memory, not fill 'SharedMemorCommand'
nor read SharedMemoryStatus directly. The C-API declares 'handles' for those,
to avoid it from happening.

Detach posix shared memory correctly
...
* shmget() fails after shmctl() is called with IPC_RMID. This patch
removes shmget() in releaseSharedMemory so that a client can detach
a shared memory correctly after a server removed it.
* A server should also detach a shared memory.
