Update ipscan to 3.8.2
Changes:
- If scanning a local network, then ARP will be used in addition to chosen Pinger to detect more hosts
- Improved storing/finding of MAC-based host comments. In LAN, they will always be MAC-based now
- Removed root-only ICMPPinger that worked using RawSockets, JavaPinger will use ICMP if has permissions to do so
- Add "allow anonymous error reports" checkbox also to Preferences to make it more discoverable
- SWT updated for all platforms
- Java 11 is now the minimum required (due to SWT), source can now be built with Java 17
- If real network netmask is known (e.g. LAN), then skipping of broadcast addresses will respect that instead of always skipping .0 and .255
- Pressing IP^ button to prefill local network interfaces will now set netmask in Range Feeder
- LinuxMACFetcher will now read Kernel ARP table directly, not relying on the arp utility to be available
- Keywords added to Linux desktop file/launcher to make searching easier
- Introduce ARPPinger for pinging LAN hosts that don't respond to ICMP, etc
