When package update fails, message should link to the log

I'm using the latest released ChocolateyGUI, and am trying update the CUDA package. The update fails - which is not your problem in itself - but the failure dialog does not make it easy enough for me to access the log and examine the failure.

We should be able to:

1. Copy the log's full path.
2. Better yet, have a link to the log which opens it in a text editor or some other application.
3. Possibly - display the segment of the log regarding the specific failure for this package.

Start by locating the failure dialog and the code that handles package-update logs. Review how the CUDA update failure is surfaced and how log paths are represented. Done means the dialog provides a usable way to access the relevant log, with the exact behavior for copying, opening, or displaying log content confirmed.
