Graal v4.02 revision 1 released

[Admins]

This is the first update for the Gold/VIP v4. Download it by connecting to the server list (login server). Updates:
- fixed the UDP mode, so it should work again, together with microphone chat
- doesn't crash anymore when there are too many explosions
- added the F1 help files
- you can switch from 3D to 2D mode again, it's not recommended though because it uses much more resources in comparison to connecting directly to a 2D server (we will work on reducing the resources taken by the 3D version)
- when disabling bitmap fonts then the text width is correctly calculated, which fixes right-aligned text
- fixed a problem with the particle emitter where after some client lag (frozen window) new emitted particles were messed up
- the sign window is displayed below the player if possible, instead of above
- when being hurt, you are sliding through other players like in v2; also when being hurt with the horse you should not get stuck in beds anymore


Gserver/NPCServer updates:
- displays correct error line if the script contains old script commands with multi-line parameters
- update packages are reloaded when an RC uploads a new version, so "reinstall" doesn't messup after modifying a package anymore
