Disables the download item on the download-shelf when the file is opened.

This is to mitigate against multiple clicks when a file takes some time to show anything to the user when opened (typically a setup.exe).
By changing the title and disabling the button, we indicate to the user that an action was taken.

BUG=7264
TEST=Download a file (image for example). In the download shelf, press the download item. The download item text should change to "Opening..." and it should be disabled (not responsive to clicks/drag and drops).
