GTK Warnings

[franzlst]

• Gtk-WARNING **: Allocating size to main_window 0x1a205c0 without calling gtk_widget_get_preferred_width/height(). How does the code know the size to allocate? (when opening RAFCON)
• Gtk-WARNING **: Allocating size to rafcon+gui+utils+dialog+RAFCONButtonDialog 0x2dec2e0 without calling gtk_widget_get_preferred_width/height(). How does the code know the size to allocate? (when opening a dialog, e.g. closing a state machine with unsaved changes)
• Gtk-CRITICAL **: _gtk_accel_group_detach: assertion 'g_slist_find (accel_group->priv->acceleratables, object) != NULL' failed (when closing RAFCON)

Sub-issue 1 and 2 can be related to size requests of widgets, e.g. in glade files.
