Graal v4.02 revision 9 released

[Admins]

Revision 9 has been released for Windows and Linux, Mac version will follow in a few days. Download it by connecting to the server list (login server).
Updates:
- supports png filter type 4 now (fixes some images)
- when a gif image has no transparency, then black is taken as transparent color, to be more compatible to v2
- updateboard has been fixed for gmaps to work for map parts close to you (not just the map part where you are standing on)
- gmaps and gupd files are updated using the checksum of the file, and are cached in memory in case they cannot be written to file, so they should always work
- the variable attr[] is protected in the new scripting engine to prevent crash (you can still modify array members, but not replace the array)
- GuiFrameSetCtrl has been fixed
- in new scripting engine serverr. vars are working now on clientside without adding a "player." in front of them
- in the Windows version the F2 log window uses the Courier font now so that things like "/party list" on Era and Kingdoms are displayed fine
- in the Linux version the default font mode has been changed so that the font is displayed correctly when you use transparent black text (changeimgmode 0 is the same like 1 now, like on Windows)
- the graphics handling in the Linux version has been optimized so that it takes less resources (the same for Graal3D)
