[Minor Bug][1B4]Validation

[Rigor O'Mortis 1]

I notice that there's validation in the "Settings" dialog. It also seems to work properly:

But as you can see from the image, the TLS port box is the only one in which it does, at least in the "Connection settings" area. I've stumbled on this little bugger when I was screenshooting the "Settings" page for a small help file that I'm working on for someone.

This bug is minor, so please do not waste time with it if there's something more important to do.

Quick edit: Also, the "password" field of the SOCKS proxy area is unmasked.
