UX: Setting options "Launch on Startup" and "Start Bitcoin on Open"

It would be very useful to have an option to auto-launch Gordian Server on boot, but this also means that you need an option "Start Bitcoin on Open".

I've fine with both of these being off by default, especially as many people may want to use Gordian Server on their laptops when they are traveling and don't want to risk having it use too many resources or privacy. But if you are using it on a Mac Mini at home, you might as well leave it on 100% of the time (especially if you can hide the interface or have it be in menu only).
