NPCServer updates

[Admins]

Today all servers have been restarted. Beside some bug fixes in gserver this also brings some new stuff for npcservers:

- /scripthelp now supports wild cards (*) and can combine type names and function name / description, that means you can search for stuff like /scripthelp player*hp

- added server-side support for TDrawingPanel: do temp.panel = new TDrawingPanel(), temp.panel.drawimage(0,0,"myimage.png"), temp.panel.saveimage(mynewfilename)

- improved speed

- added more stuff in /stats (shows memory usage) and admin-commands for analyzing the engine speed (so I can help better in certain cases)

Update:
- urlencode(string) - encodes urls for http GET requests (TSocket)
