Request: prevent sleep mode with Windows

[Hexaae]

Request: add option to prevent Windows entering Standby/Sleep mode, as other apps do.

Please, this is a fundamental option or Windows at night will enter sleep mode due to inactivity, and of course I don't want to change power saving modes of the operating system every time just because Picotorrent is running :(
...nor I want to be forced to run programs like Cofee to monitor network activity and prevent sleep for a function that should be built-in in every downloader.
