Delete old import files when patcher starts

\SkyProcDebug\Mod Imports can grow to be huge over time since files are never deleted but instead overwritten if they already exist. The folder should be cleared when the patcher starts to ensure they don't get out of control.

This is actually an issue with Mod Organizer as SkyProc attempts to delete all logs on startup. I have requested more information from the STEP forum on how to fix it.
