ConfigParser is module which parses commonly used 
INI files. It gets sections from file and values from 
sections. By now, it gets from file key and value divided 
by symbol ":" or "=".

For FTN application, a want to use FTN addresses as 
keys. FTN address looks like "2:5020/12000". So if I try 
to use it as key, ConfigParser considers "2" as key 
and "5020/12000 = ..." as value. 

I made patch, which allows to use any set of symbols 
(or '=' and ':' by default for compatibility) as delimitier 
between key and value in INI file.
