Allow to save Console output to file

[SebastianZ]

This was initially reported in issue 6545.

• a DETAILED DESCRIPTION of how you imagine the feature

I imagine a simple: right click -> save as...
Opens a save menu.
Allows for saving to a text file.

• a TEST CASE (no matter how trivial)
  add:
  Firebug.Console.log(targ);
  to:
  onInspectingClick in firebug-lite.js

This will add the HTML code of the inspected items to console.
Next, in the console window, right click -> save as...
Save the log to a file.

What should be implemented/improved?
Console Output to file.

Browser version: Preferred Chrome (Firefox,etc...)
Operating system: Any

Thank you!
