String :: fromCString - Convert string from C-string

C-strings are strings that could be defined as string constant in a C program. C-strings must not contain several characters, wich are converted as follows in order to normalize the string:

• \\ ==> \
• \n ==> newline (10)
• \r ==> carriage return (13)
• \b ==> backspace (8)
• \f ==> form feed (12)
• \t ==> tab (9)
• \" ==> "

Conversion is done inplace. In order to create a C-string toCString() may be called.
