GGU-RETAIN: "Heave of anchor soil" menu item

If a value unequal to '0' is entered for the height of the dead man when entering the anchors in the dialog box associated with the "Editor 2/Anchors" menu item, the program performs verification of anchor soil heave similar to the method described in Section 7.3.4 of the Piling Manual.

This menu item displays the results in a message box. Verification must be activated, of course, (see menu item "Editor 1/Deep-seated stability/heave of anchor soil").
