ReplaceMemberNames

As discussed in issue #471 member names can be partly invalid due to spelling, language or other reasons.

This submit can help you map rules to those bad naming conventions.

Words like Äviåtor can be renamed to Aviator with rules like:

var mappingOptions = new StubMappingOptions();
mappingOptions.ReplaceMemberName("Ä", "A");
mappingOptions.ReplaceMemberName("å", "a");
