Title: Introduce Terminate exception for 'expected' exceptions

This patch introduces the Terminate exception, and changes all FATALs which do not indicate "serious" problems but rather ones where no backtrace is helpful (missing arguments, file not found, etc.).

In addition, exception passing from the threads to the main program is implemented.
