Fixed my tests breaking!
Removing 8.0 specific partial classes - it is not the "main" version.
Removing some old 6.x and 7.x sdk files.
major tests refactoring:

Removed redundant attributes
Made tests load the nuget package of the container - no more direct references
Streamlined base test fixture
Adding a WordIndex to check if a file is using any references (words) that belong to a specific container.
This also fixes #60 - using placement no longer relevant.
Merge pull request #61 from hmemcpy/develop
