[cvsnt] OSX issues with 2.5.01.1910

[Miklós Fazekas]

1. Installation didn't work, i've always got a preinstall/preupgrade 
failed.
     It seems that preinstall/preupgrade should exit with 0 status code, 
so i've insterted an 'exit 0' to the end of these scripts.
2. When i commited a .sh file it got commited as binhex, and not as 
clear text, why???
     If i don't need this binhex stuff, how can i disable it?!
     (The file contains a resource some editors like CodeWarrior adds 
resource fork to text files that contains only fonts/tab information)
    The finder recognizes the file as CodeWarrior source file, so i 
don't understand why do cvsnt encodes it?!
