Merge remote-tracking branch 'origin/master'

1.14 & 1.15 bug fixes!(entity velocity error and api not starting up fixed)

Now fully works on 1.7.10->1.15.2

Stable build!

-# PacketEvents
-Listen to minecraft packets and send minecraft packets.
+# packetevents by retrooper
 
-Credit to TinyProtocol
+An asynchronous spigot packetListener coded by retrooper.
 
-PacketEvents coded by purplex.
+Credit to TinyProtocol, PacketEvents uses a modified version of [TinyProtocol](http://github.com/dmulloy2/ProtocolLib/blob/master/TinyProtocol/src/main/java/com/comphenix/tinyprotocol/TinyProtocol.java) by DeprecatedLuke to support 1.7.10 & 1.8.
+PacketEvents does some extra modifications to support the rest of the versions!
+All I do is make the wrapper classes and useful utilities that support 1.7.10 -> 1.15.2!
+This packetlistener is supported on spigot servers(Spigot, PaperSpigot, ...).
