Add support to run on startup

[aditbajaj]

Please add support to run on startup. I haven't tested but I believe I could manually do this by running the portable executable hidden on startup, although this is rather cumbersome.

Edit: it seems that there is no bundled Neptune CLI for Windows, so even the solution I proposed above is not possible.

Edit: just read the docs again, turns out Neptune GUI is bundled with Neptune CLI. Created a scheduled task using run-hidden.exe manually. Works fine. Though I'd still like to see this built in.

Thanks for the idea, i'll add it in the next release.
