Fixed generics and var, out and more than three parameters

[jho1965us]

Fixed problems with:

• generic methods,
• methods in generic types,
• var parameters,
• out parameters,
• methods with more than three parameters

New feature:

• apply NeptuneAttribute to type/method to enable/disable making it injectable

It is backward compatible with the latest Virtuoze/NConcern (Latest commit 719d506 on Jun 6, 2017) But to actual weave generic methods and methods in generic types a newer NConcern is needed too.

For the final preparation of a pull request for NConcern I need a working NuGet Package of this version of CNeptune. Unfortunately I will not be able to work on that until next week (alternatively you can take the currently latest jho1965us/NConcern commit a801994, and fix the nuget package reference there your self). Test cases for changes in this commit is part of the work done on NConcern.
