Run Updater as administrator when Dolphin is in a protected folder

[superluig164]

The Updater should be requested to be run as administrator (using UAC) when Dolphin is in a protected folder, for example Program Files. If I do not run Dolphin itself as administrator, the Updater will just silently fail to update at all, with no warnings or suggestions. Additionally, you can't run the updater on its own to just update Dolphin (which frankly, is stupid) so it's currently impossible to auto-update without running the main program as an administrator. Instead it should ask to run the updater as administrator when you click Install or whenever you close Dolphin and it begins the update.
