Another commit in my long series of cleaning the technical debt in Dandere2x.

Changes from 2.0

• New console with more descriptive and clean printing. Currently does not save to a file.
• Removed 'quality_moving" images, since block matching needs to be R&D'd better.
• Added error indicating the user may of not downloaded the externals files needed (received PM's about this)
• Uses CV2 to count the number of frames in a video (hoping this will reduce some bugs)

Notes

• "DAR" is not added here - still cleaning technical debt on how to handle this cleanly.
