Add newline before printing "Download complete"

[JohnVeness]

While you are downloading a file, the progress indicator appears. When it is finished, "Download complete" is printed. However, this overwrites the progress indicator, looking messy. So you see things like:

Download complete: 32.00 KB.15 KB of 32.00 KB, 50%

It would be good to do a newline before printing "Download complete".

Also (maybe should be a separate issue), it would be good if the progress indicator could get to 100%. It always ends earlier than that, usually 99%.

If the intention is that the "Download complete" line should overwrite the entirety of the progress line, that could be done instead of doing a newline first, but either way, the current output is messy.

Moreover, the current progress bar is broken on certain shells, resulting in a flooding progress bar wall of text.

@V10lator Many thanks for this. Is your fork published on github (or similar) so we can see commits etc?

@V10lator - goof stuff thank you for sharing!
Yeah if you submit a pull request I'll accept into the main repo.
Have a go, otherwise in a few days I'll just do it myself.
Thanks

@JohnVeness @llakssz My PC is defective, I'm doing this with the help of a live DVD. That's why there are no commits and no pull requests.
Anyway, I'm still coding while we speak. Current (untested) changelog:

• Remove Python 2 support
• Resume downloads
• Handle server / connection errors correctly
• Allow numbers higher than 9 for the retry count
• Overwrite lines on CLI correctly
• Close file handlers correctly
• Return one in case of error so the CLI gets informed correctly
• Fis issue Case (in)sensitivity on config-saved keysite URL. #45
• Use a default chunk size of 4 kb / fix bug chunk_size=0x4096 strange? #35
• Fix bug "Content download not correct size" for 0005000e10112200 #33

I'll try to get access to another PC, rebase everything into commits and try to pull them next days but no guarantees on that.

No problem, I'm sure we all have patience! :) Thanks again for the work.
