Add/fix passing of configuration from CLI.

Configuration options:
- type sharing
- accessor creation
- nullable constructor parameters.

Also reordered parameter to separate it from options which it is not.
Add support for not generating include_once statements.

This may not be useful/optimal when using autoloading or the like.
Merge branch 'refs/heads/no_include'
