Synology DownloadStation fix

[HaverKhrone]

Hi,

I updated SynologyWebUI.js to use synotoken instead of sid - according to
https://global.download.synology.com/download/Document/Software/DeveloperGuide/Os/DSM/All/enu/DSM_Login_Web_API_Guide_enu.pdf

Now it is working great!

Tip: you can create multiple accounts on Synology NAS - on every account in DownloadStation selecting different default location for your downloads,
then add accounts to RTA and in a result you will have in a context menu the choice where torrents will be downloaded.

Cheers
