dev-manual: Added yocto-layer script note and updated kernel version
I added a bit about the layer creation in the patching the kernel section. The example does it by hand and now you could obviously use the yocto-layer create script. I made a note of saying the example does it by hand. Also, in the menuconfig example. I updated the kernel version from 3.4 to 3.14. It was very old.
