orxonox/trunk: moved likely to compiler.h in defs
also reset all the UNLIKELY_IF functions to how they should look.
the old approach is still valid, but depricated.
@patrick: i hope this is ok for you, for it is LINUX-standard.
and i think windows is also able to handle likely/unlikely because it is a compiler issue not a system issue
