Add a message box to display fatal errors

As we saw with NXDRIVE-605, in case of unrecoverable database, Drive will exit without noticing the user what happened. In fact, there is an exception but it may happen too early to be logged.

The user will just see cryptic message even our developers could not understand because there is absolutely no information.

The idea is to display a message box:

• saying there was a fatal error
• automatically generate a report and display the link (if it does not work, skip it)
• a text area with last lines from the in-memory logger, if available
• a text area with the exception
