Added the beginning of the bring machine online use case. Added a handler to act as new machine. Added a form to post the account number and serial number to the handler. Had the handler lookup the machine and return it for now. Began testing 'multi-tenancy' of machines. Found that all machines were returned rather than just those for the user account. Added support for 'multi-tenancy' based on user as the parent. Tested that this mostly works. More testing will be needed from here, but it looks like it works.
