Error Reporting: Complete

[dclear]

What happened (or feature request):

In #42 we closed out basic error reporting for the alpha release of ddev-ui.

For a later release, we'll want to deal with Complete error reporting. From 42:

3. Terminal Output, Normal Mode: Show the normal terminal output that is coming through as ddev CLI is running commands.
4. Terminal Output, Verbose Mode: Essentially toggling on/off debug mode for DDEV CLI and reporting that output.

From a visual perspective, we need to do this in a way that doesn't overwhelm the interface, particularly items related to 3 and 4.

Anything else do we need to know:

This needs to be spec'd out.

The other ticket was really about handling errors within ddev-ui. That's still super important. It wasn't just about handling problems with the project.

I don't think this problem has been well understood. For example, if ddev-ui has an error interacting with ddev, it should say so and not present a blank screen.

@rfay : sounds good, if I misunderstood re: the other ticket, we can either reopen it, or use this one. (The other issue wasn't determined to be a blocker for the v0.4.1 alpha we are trying to get out tomorrow). We need to flesh out details on this one, too.
