Subject: (svn r3322) - Fix: Network window crash when it receives invalid
 information for example from the integrated nightly, so validate the
 network-input when it is received - CodeChange: added str_validate(char *str)
 function that checks if a string contains only printable characters and if
 not, replaces those characters by question marks. Also move
 IsValidAsciiChar() to string.h
