getSetting: add an optional scope parameter

settings are stored in 3 places:
- login (.gpg file)
- store (.browserpass-settings.json)
- extension-level config (browser UI)

but we don't want each setting to be settable everywhere, so scope
allows one to control which of these 3 places to search for a given
setting.
