load the per kernel kernel.js and kernel.css...

load the per kernel kernel.js and kernel.css As per discussion, each kernel can provide a file name kernel.js that we try to load at kernel switching. If such a file exist we assume that the kernel pathches the javasscript and that this javascript cannot be unpatched, and further switching of the kernel cannot be undone without reloading the page. (separate PR for UI) if a kernel provide kernel.js, the it should consist into a AMD module definition that uses require.js the module shoudl define a function name `onload` that will be called at the appropriate moment before the kernel starts.
