	* src/dialogs/analysis-tools.glade,
 	src/dialogs/dialog-analysis-tools.c: Implemented Glade dialogs for
 	T-Test tools.

	* src/dialogs/dialog-autosave.c: Fixed a few bugs in
 	dialog_autosave (cancel caused segmentation fault at the next
 	run).  Made the prompt button unsensitive if the autosave is
 	turned off.

	* src/analysis-tools.c: Made the titles to be printed in italic
 	style for Correlation, Covariance, F-Test, and T-Test tools.  In
 	addition, the columns are autosized.
