Limit Ports for Applications - e.g. SSL only

```
What version of the product are you using? On what operating system?
1.5.7

Please provide any additional information below.

First: Thanks for this great APP!!!

Feature Request:
It would be great to have an additional checkbox for every APP to limit the APP
to TCP/UDP connections to Ports that are used for SSL encrypted connections.
e.g. 443 (HTTPS)

This does not force encryption. Applications can still transfer unencrypted
data on SSL Ports, but it is not very likely.

GUI Example:

Wifi 3G Name SSLOnly
[ ] [ ] NameOfApp [ ]

Additionally I would recommend to open the following ports for such
applications:
nsiiops 261 IIOP Name Service over TLS/SSL
nntps 563 nntp protocol over TLS/SSL
sshell 614 SSLshell
ldaps 636 ldap protocol over TLS/SSL
corba-iiop-ssl 684 CORBA IIOP SSL
ieee-mms-ssl 695 IEEE-MMS-SSL
ftps-data 989 ftp protocol, data, over TLS/SSL
ftps 990 ftp protocol, control, over TLS/SSL
telnets 992 telnet protocol over TLS/SSL
imaps 993 imap4 protocol over TLS/SSL
pop3s 995 pop3 protocol over TLS/SSL (was spop3)

The issue does not identify implementation files, tests, or an entry point. Begin by locating how per-application TCP/UDP rules and the settings UI are represented, then determine how SSL-only port restrictions would be configured and tested. Done means an application can be limited to the requested ports without changing other rules.
