commit 62a3acd978daee61b3ea99b4cd705d4401203ee3
Author: eroman <eroman@chromium.org>

Cosmetic changes to chrome://net-export, primarily for desktop mode.

 * On the desktop UI, remove reference to emailing from the instructions
   (as that is only available from the mobile version).

 * While logging is in progress, change the disabled button's text from:
     "Start Logging to Disk"  to "Logging to Disk..."
   This gives a bit more feedback that something is happening (even
   better would be to show the path to log file and its size)

 * Add a <title> for the page of "Network Log Export"
