[Usability] HIG: Small patch to "Progress windows" section

[Matthew Paul Thomas <mpt postinbox com>]

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.)"
