HIG: Small patch to "Progress windows" section

This patch makes small changes to the HIG's "Progress windows" section.

*   New: "A progress window should always appear as an independent
     window in a window list. If progress of a task makes a window
     temporarily unusable, do not present a modal dialog-like progress
     window in front of it. Instead, present progress somewhere in the
     original window, making all its other elements temporarily
     insensitive."

*   Removed: "Progress windows should have the same title as their
     primary text." (This guideline has often caused redundancy in
     progress windows, e.g. 
<http://www.dedoimedo.com/images/computers/pendrivelinux_ubuntu_installing.jpg>. 
It also usually causes the window
     title to inappropriately use header capitalization.)

*   Added: "Progress windows should have a title representing the
     overall operation: for example “Copying Files”, “Installing”, or
     “Calling”. (As with other window titles, do not end progress window
     titles with an ellipsis.)"
