update IP before each connection retry

Hi !
I'm downloading from a FTP which IP is changing sometimes.
It seems that after disconnection, SmartFTP try to reconnect to the previous IP instead of resolving host and get the new IP.
So I restart SmartFTP and it's working.

Then a great feature could be :

In connection settings :
checkbox : update IP after reconnection failed x times

bye :wink:

PS : I use ver 1.0.978
