Improvements

Content:

• Fixed: #8 (closed) - flag added
• Fixed: #7 (closed) - instead of adding flag decided to always validate and show validation errors + if verbose flag is enabled then additionally inform about detected stuff.
• Fixed: #5 (closed) Added default values for mostly used cmake parameters
• Added feature which allow to save and show command line incantations used previously with hell for current project and for current user account - this is useful specially for long incantations or when you just want update project and not remember it details. User scope is pretty much equal to ctrl+r in bash but on windows this feature is missing in psh/cmd. Anyway project level history of incantations can be helpful on all platforms.
