Title: Download error handling: certificate

Added VOSpaceErrorHandler class which gets invoked when there is a problem downloading something from VOSpace. Currently it just knows how to handle CADC certificate problems: it pops up a dialog for the user to enter their credentials, downloads a new certificate, then tries the image downloads again.

Closes #49.
