(svn r221) -Feature: console command and variable hooking

-Fix: added another network.c stub
-Consolecommand: "scrollto <tile>" center main view on <tile> [Darkvater]
-Consolecommand: "resettile <tile>" force bulldoze <tile> without any checks (DEBUG only) [Darkvater]
-Fix: resetengines is hooked to be not available in network games
-Codechange: "connect <connectstr>": the connect command now uses a connectionstring like the network-gui
-Fix: Direct Connect editbox can handle up to max ~35 characters [Darkvater]
