798b70c Be even more defensive about half valid items in hover events While they aren't particularly useful or intended, they were valid

1.20.5 client support; this one of the largest updates network-content wise, so expect rough edges. I'd also like to thank the wave of sponsors as well as the people that showed understanding for the 3 day delay. If it weren't for the sponsors, this update wouldn't have been even close to being usable already.

Important: The ViaVersion update for 1.21 will require Java 17 or above

• While we will still offer additional magical jars for Java 8 compatibility on releases for the foreseeable future, you should still make sure your server can run on Java 17 by then
• Even 1.8 servers can run Java 17. Most 1.8 server forks will also have proper support for it
• Some versions have an arbitrary/unnecessary Java version check from Spigot that prevent startup:
  • For 1.16 and 1.17, use Paper's -DPaper.IgnoreJavaVersion=true startup flag
  • For 1.13 to 1.15, use any updated fork that just removes it. An unsafe (!) way of skipping Spigot's check is by using -Djava.class.version=<supported Java class version>

Fixes to previously added version support

• Added a large number of sanity checks to NBT reading to prevent errors from bad data
• Fixed Entity sound handling in some >1.19 protocols
• Fixed text components that are too long kicking 1.20.3 clients
• Fixed handling of null json entries in text components in 1.20->1.20.2
• Fixed 1.15->1.16 item attribute uuids
• Fixed various issues with text component handling in old protocols (by EnZaXD and RK_01)
• Fixed 1.12->1.13 enderman held block handling
• Fixed lots of text component translation issues in 1.8->1.9 (by EnZaXD)
• Fixed an issue with non-lowercase sounds in 1.8->1.9 (by EnZaXD)
• Ignore errors in custom payload reading in older protocols as per vanilla behaviour (by EnZaXD)
• Fixed an error when creating dumps on Sponge (by EnZaXD)

Also thanks to EnZaXD for lots of aid with 1.20.5, as well as RK_01, DrexHD, and Gerrygames for additional fixes!
