492c6dc1e742a62599dc6d5ba6c3896825b5144f util: change GetWarnings parameter to bool (John Newbery)
869b6314fd180856b6054fff28b5de994252c54c [qt] remove unused parameter from getWarnings() (John Newbery)

Pull request description:

  `GetWarnings()` changes the format of the output warning string based on a passed-in string argument that can be set to "gui" or "statusbar".

  Change the argument to a bool:

  - there are only two types of behaviour, so a bool is a more natural argument type
  - changing the name to `verbose` does not set any expectations for the how the calling code will use the returned string (currently, `statusbar` is used for RPC warnings, not a status bar)
  - removes some error-handling code for when the passed-in string is not one of the two strings expected.
