Portranges is done with one rule per port

[Kim Alvefur]

When setting port ranges, Gufw adds one rule per port. This takes a long time.

Steps to reproduce:
1. Start Gufw
2. Select the Advanced tab
3. Add a rule like Allow tcp from any to Any 8080 8090
4. Click add

Expected result:
One rule, To=8080:8090
Corresponding ufw command:
ufw allow proto tcp from any port 8080:8090

Actual result:
10 rules, {To=8080, Action=Allow, From=Anywhere}, {To=8081, Action=Allow, From=Anywhere}, etc
Corresponding ufw command:
for port in {8080..8090}; do
  ufw allow proto tcp from any port $port
done

Version: 0.20.7-0ubuntu2

Hi!
ufw can't add a range without protocol.
Gufw add the improvement for add rules for both protocols at same time.
Sorry, maybe in the future I change this.
thanks by bug ;)
