release v1.7 - stub mocks method class, locate concrete types of interface params, expose configuration for IDE scripting tool

[yaronyam]

Features in v1.7 release:

• Generate mocked return values for method calls of mocked dependencies in tested class
• Test params generator: locate and initialize concrete types found in project source instead of passing null for interface/abstract parameter types
• Get configuration from system properties (a temporary solution to support runtime configuration control via the built in IDE Scripting Console - on the Tools menu). Note: Some of these configuration properties may not be supported in future releases. More info and usage instructions here
