Ticket #427 (enhancement)

Why?

Sorry, my english is very bad, i can't mean instead i can mean also.

ConfigParser is util in many cases (99%), but sometimes is necessary RawConfigParser (ConfigParser replace variables in value of the config files).

The overload of optionxform function in CaseSensitiveConfigParser class is very usefull. This is the reason to add this feature to this library, and not use RawConfigParser directly.

pardon to confuse instead by also

do you think that could be usefull add the RawConfigParser functionality?

With this change, I can use dict_from_config_file function to get quickly a config for my app.

With raw parameter set to True, I can read easily messages for use with formencode api. A example message in formencode validations:

messages = {
        'tooLong': "Enter a value less than %(maxLength)i characters long",
        'invalid': "Invalid value (value with length expected)",
        }

The tooLong key is problematic because have the maxLength variable. With raw read, there are no problem.

I haven't got idea of a realistic example of convenience of vars parameter. But is cheap add it, and it could be useful.

PD: The authentic revision isn't 1343, this is my local revision because I use SVK

Implemented in [999].
