Enable more tests from test_format and test_long
* implement __format__ for integers * proper impl. of complex and float format with no type specifier * support also _ as explicit "thousands" separator (with group size 4 for oct/hex/bin) * improve compatibility with CPython in validation of format strings * basic implementation of locale aware formatting by delegating to JDK
