[issue9421] configparser.ConfigParser's getint, getboolean and getfloat don't accept `vars`

Patch included.

New type-related unit tests have shown undesirable behaviour of read_dict() when the given option values are not strings. Support for numbers, booleans and Nones is likely to be expected so this change was introduced. `default' can hold a non-string value. `vars' were modified to accept other types as well, for consistency.
