Subject: [PATCH] RecastMeshDetail.cpp: Fix compiler warning

Function 'updateLeftFace' is static, and when 'REVERSE_DIRECTION' is set to 1, its not getting used anywhere leading to a compiler warning as it has internal linkage with no references, and thus its getting pruned. Only define the function when 'REVERSE_DIRECTION' is 0.
