Title: fix ThreadSafeMessageBox always displays error icon

- allow to specify CClientUIInterface::ICON_ERROR / ICON_WARNING
which are then used for displaying the message box in the UI
- remove CClientUIInterface::OK from ThreadSafeMessageBox-calls, as
the shown message boxes always contain an OK button
- some small fixes related to not using _() and such
