Command Line Usage still force user to use dialogs

[muchamaciek]

The tool is amazing, and now works way much better still does not allow to be used as a commandline tool for images for two reasons:

• it does not allow to run on sequences starting not from 0 (so starting with frame 600 is not possible), so you cannot run it in batches, or in case of fail, you have to run it again from 0
• when using a single picture input (so literally written number, like: "Frame_00569.png" it opens a dialog with a question if it is a sequence or not. It should be possible to force him do the image which is not a sequence.

Yes, that is true, that is a limitation of the implementation in opencv.

This should not happen. Will check.

Need to test on Linux - on Google Cloud Shell, errors like

./ocvwarp OCVWarp.ini hanu0018.jpg "hanuW.jpg"

Could not open the output video for write:

./ocvwarp OCVWarp.ini hanu0018.jpg hanuW0018.jpg

solves the problem. If input has zeros/numbers in filename, output filename also should have!
