Fix crash when 7-zip fails to extract a file

A thread is spun off to handle the extraction while the main thread handles the progress bar updates.  Previously, a dialog was spawned in the thread when an error in 7-zip occurred.  Now, the thread will terminate and pass the error message back to the main thread who will spawn the dialog.
