tasks: handle carriage returns in task output

Browse Source 
When we're running commands as part of a task that use carriage returns
(\r) to update the currently displayed line, we want to see the same
output in the web representation, so if we encounter a \r in the output
we need to look back to the last newline, truncate to that and then
start appending.
