For normal development work, use 'Debug' configuration. When you are working in
this mode, you should make sure that the /skipRepairAttempt command line
parameter is present in the Debug tab of the 'paintdotnet' project's properties.
Otherwise, Paint.NET will see that some files are missing and attempt to repair
itself. Not all of these files are necessary when doing development or debugging.
