Unzip directory removed from config if directory not available at initial scan

[gyoung]

One other thing that I have noticed is FM2 eliminates the designated unzip directory is the directory is unavailable at the time FM2 scans on opening. (Very annoying when I fail to notice and unzip a large zip file in a directory containing several thousand files) My unzip directory is on a network drive and I start FM2 from a startup folder so even with the xworkplace delays between programs FM2 beats the requester. As a result I have to go in and reenter the unzip directory in the setup. It should leave the directory and if at the point that I try to to unzip something it is still unavailable give an error message.
