Title: allow PascalCase for case identifiers

For command line arguments, PascalCaseParameter becomes --pascal-case-parameter,
and for App.config files, it does key="pascal case parameter".

I think it would be nicer because F# prefers PascalCaseName to Underscore_Name.
Note that this is a breaking change.
