Limit syncs to a configurable interval

[michaelarnauts]

Right now, every time WiFi is turned on, the sync will start. This causes the Kobo to sync every time something is looked up online (online search, actual sync, ...). I think it would make sense to only sync once a day, or (if possible), tied into the actual syncing to the Kobo service itself.

Also, right now (with the nextcloud integration, but I assume it happens with every integration) it tries to download every file (curl does something to check if the filesize had changed) and this can take quite a while. Maybe it shouldn't try to download files that are already on the device? You can always delete them and they will be redownload anyway.

I was wondering whether it would be possible to add a button to Nickel Menu that would trigger the sync on demand. Maybe this would reduce the overall overhead of unnecessary syncs and help with https://github.com/fsantini/KoboCloud/issues/113?

You dan influence the sync with enabling/disabling the WiFi. Just put out WiFi, will save your battery as well (even without KoboCloud).
