qview does not take a -pref command line argument
Minor - Impacted Isis Applications include all QIsisApplications.
qview does not accept a command line argument to allow the user to set their preferences. This causes a problem when spiceinit was run using a special preference file and a kernel location set using one of the Isis environment variables e.g., "lro", "mro". qview can not find the kernel file so it fails to create a camera therefore the user sees no lat/lon
In work project there's an IsisPreferencesTemp file that can be used to test against.
There's a DataDirectory group at the bottom that can be modified to change the path in which the mission data points to.
By default it's $ISIS3DATA/[mission], however this can be changed to point to wherever the user has that mission data stored.
