In MyPasswordSafe, if a field was blank I wasn't saving anything. This
was causing some problems in Password Safe. For example, if an entry was
not in a group MyPS would not create a group field for that entry.
Password Safe would then place that in the last group it encountered.
I just made MyPS save empty fields, but I think on the Password Safe
side that any variables that are used to read fields need to be cleared
for each entry, especially the group field.
