patch on jolly/menu for jumper app

Here is a patch for a simple "jumper" app which loads at 0x2000 and which disables the irqs (thought it might help with the nuttx startup error I have) and jumps to 0x10000 (where I have flashed nuttx). I'm submitting a patch to nuttx as well for building nuttx.bin for running in compal_e86 flash. I may have fouled up the patch due to being on jolly/menu. Wasn't sure if you wanted to pull in those changes as well? I've certainly used the menu app with the flashing_new instructions and it seems to work great on my c139. -Craig
