[Bug]: Screenshot export does not require the user to pick a location

[kwvanderlinde]

Describe the Bug

In the Export Dialog, if the Filesystem tab is active but no Location has been chosen, clicking Export will create a screenshot based as a sibling to the working directory.

To Reproduce

1. Open a campaign.
2. Go to File > Export > Screenshot.
3. Click Export without filling the Location field.
4. Go to the working directory
   • This varies based on how you run MapTool. To find it, go to Help > Gather Debug Information, then look for the User Dir. under ==== User Information ====.
5. Go one directory up.
6. Look for a *.png file with the same name as the working directory from (4). This is your screenshot.

Note

If MT doesn't have permission to write to the parent of the working directory, there will be an error message shown and no screenshot will be written. This repro requires permissions for the given directory.

Expected Behaviour

The export should not happen until the user pick a location.
