pathCache search keeps searching even after file is found

if you see this for loop, it will always loop until the end of the list is found, ideally you'd stop once PHYSFS_ENUM_STOP was returned, (file was found)

for (size_t i = 0; i < fileList.size(); ++i)
			if(openReadEnumCB(data, dir, fileList[i].c_str()) == PHYSFS_ENUM_STOP)
				break;

this is likely why #246 has gone unnoticed.
