Implemented use of multiple accounts to fetch data, links and search-results
1st account is primary (duh!) so any Band-/Album-info will be in the language and region associated with that account.
If however that info is not available to that account the next will be used with it's assigned language and region.
Config in user directory is now the primary config.
