Listen on localhost, accept only one connection.

Converted from SourceForge issue 1873689, submitted by ars3niy

Currently wxMaxima listens on 0.0.0.0:4010 which allows anybody who can reach me over LAN or maybe even Internet to interrupt my work (by doing netcat my.machine 4010 and then Ctrl+C).

The first patch makes wxMaxima listen on 127.0.0.1:4010. The second patch makes it reject all subsequent connections which makes it almost impossible to interrupt work even from localhost.

The first patch (wxmaxima-listen-on-localhost.patch) breaks wxMaxima on my MacBook. After applying it wxMaxima is unable to start the server. I didn't investigate why this happens. wxWidgets documentation suggests that AnyAddress should be used instead of LocalHost if possible, so I will reject the this patch for now.

The second patch (wxmaxima-accept-one-connection.path) looks OK so I will commit it.

Thanks for looking into this.

I've read something about problems with resolving "localhost" on Mac. If this is the case, addr.Hostname(wxT("127.0.0.1")) instead of addr.LocalHost() may work.

Changing to addr.Howtname(wxT("127.0.0.1")) didn't work either.
