Get Analyst Client to retry updates

Due to antivirus and other protection software, and the way the Analyst Client performs its deployment update, it often crash.

This seem to be caused by the download, extract to a random folder name, and then rename the folder.

The recommended solution of disabling antivirus, is not doable for many customers, as their IT department have locked down antivirus changes.  Plus asking the IT department to disable antivirus everytime a deployment area gets updated, is not feasible.

I think the solution is to capture these problems, and retry a few times with random delays.  This might make the updates slower, but at least they will work.  It will also allow the software to give better error messages if a module will not install.
