Feature Request (UX): ship booting queue

[neonfuz]

Right now if I want to boot many ships on groundseg, I have to wait for each ship to finish it's boot before uploading the key and selecting options for the next ship. It would be nice to be able to queue up booting ships by starting a boot process, clicking back, and clicking new ship again. Consider appending the booting ship to the path, like /boot/new/sampel-palnet so the user can revisit the booting screen for each booting ship. A list of booting ships with links to their boot page would be nice too.

You probably want to implement a queue which only boots a single or a few ships at a time to prevent slamming the cpu with many ships booting in parallel.
