Feature request: show summary at end of scrape

[melithine]

I really like the colored summary information displayed when there are multiple users being scraped, but the output for the entire scrape process often exceeds my scrollback buffer (particularly when using ConnectBot as my SSH client on my tablet. It would be nice to have a feature toggle that would simply show the scraping stages as they are now, but only output the per-creator summaries at the end of the run. This seems like a good project for me to work on, as I feel that this is withing my comfort level for my knowledge of C#. Posting here first in case you want to object or provide any specific guidance on what to do/what not to do.
