If the PTOptimizer exits, hugin reports the current errors in the dialog.

I think the optimizer integration should be completely rewritten. Actually
almost all code to use libpano directly instead of calling PTOptimizer
externally is already there.

The only problem is the progress reporting of the internal panotools
functions, which cannot be customized and behaves completely differently on
windows than on the other platforms. I will probably submit a patch to allow
an application to supply a callback function to intercept the progress
reporting.
