Better support for servers

I run my Zorro instances on a Windows server and there are a few quality of life improvements that would be really valuable:

• Persist strategy inputs between runs (biggest one being the capital slider)
• Add live trading as a command line option (in addition to the existing Test and Train)
• Persist history when resuming an algorithm (so the generated web page is still useful after a reboot)

My greatest wish is for the server to reboot and have everything running after a power outage with no human input. At the moment every time the server loses power, I have to RDP in and set up all my Zorro instances yet again.

A moonshot: Automatic unattended updates.

If you have Zorro S, use commandline flag -c accountname to select a live or demo account.
