Darkvater eea9e95278 (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
