Very bugged 2.0.0

[linuxuser1]

In the new version 2.0.0 there are many bugs:
-It creates a copy of you in tab and after you disconnect you can't rejoin until server restarts.
-The gui can only be opened by the feet.
-You can only open the gui one time and then it's gone forever.

Please fix all of this and add configurable messages to traduce them.

@unldenis Also, the build failed, so it's not accessible via Jitpack (Maven): https://jitpack.io/com/github/unldenis/Corpse/2.0.0/build.log
