[Bug] + [Feature] incorrect operation "podroid-forward list"

[red7nikotin]

Description

The command "podroid-forward list" does not work correctly, outputs only part of the actual list in the terminal.

Steps to Reproduce

Setting up an FTP connection

1. Add port^
   for port in $(seq 30000 31000); do podroid-forward add $port $port tcp done
2. Show port table
   podroid-forward list
3. See error
   Only a part of the list is displayed, not all 1000 ports.

[Feature] Need add vertical combo box + vertical scrolls bar

It is necessary to provide in the main window of the program the possibility of using a drop-down list with a separate nested scrolls bar vertical, because the list of necessary ports can be very, very huge, and the user will get tired of flipping through the entire page to see all the parameters that are displayed at the bottom of the settings window of all current podroid itself.

[Feature] You need to add a search to the list of dropped ports.

If there are a lot of ports, in addition to the combo box, you need to implement a search in order to be able not to scroll through an endless list, but to immediately perform a search and make sure that the desired port is forwarded.
