Update to 1.19.1 (#772)

Quellcode durchsuchen 
* 1.19.1-rc1

* More signature changes

* Further 1.19.1 changes

I also started on the checkstyle update, see the developers notes
for the rest I haven't gotten around to fixing yet.

* Fix checkstyle

* Checkstyle imports

* Fix logic error

* Changes 1.19.1-pre2

* 1.19-pre3

* Progress, some parts still WIP

* Overlooked changes

* Fix ServerData

* Fix ServerLogin send check

* Workaround the broken behavior of "No Chat Reports"

Note that if we ever choose to enforce chat signatures, then the mod will just break again... not our fault if we do that, you get what you pay for.

* more
