clear code log button

The cf-view window has a log of code and errors on the left. This can get long and include many things not of interest. It would be good to have a clear button (and a save button) for that window.

Good idea. Noted as a useful feature request, though can't tell when I'll be able to find time to address it (maybe one for our hackathon, at the latest).
