- Change bitcoinamountfield to use locale-specific number format - Change bitcoinunits to show and parse locale-specific numbers - If a language/territory is selected in options, this is set as default locale (overrides system locale). Fixes #3887 (cherry picked from commit laanwj/bitcoin@db0b8f3a2e, bitcoin/bitcoin#3893)
