[Feature] Add presets

[Redsandro]

Would be cool to be able to set custom named presets. E.g.:

• eBooks
  • Download To: /deluge/incoming
  • Move Complete: /Documents/eBooks
  • Add paused: false
• Movies
  • Download To: /deluge/incoming
  • Move Complete: /Movies
  • Add paused: false
• Music
  • Download To: /deluge/incoming
  • Move Complete: /Music/downloaded
  • Add paused: false

Then you can

• Right Click >
  • DelugeSiphon >
    • Add
    • Add with options
    • eBooks
    • Movies
    • Music

And upon choosing a preset, the name should become a label inside Deluge.

I made something similar in my plugin for the Seagate Personal Cloud… it's a little tricky generating the context menu buttons dynamically, here's how I ended up doing it: https://github.com/Ern-st/SPCDownloader/blob/master/src/assets/js/main.js#L124
