0.3.2b2 - Many GB temp files left undeleted

[Milincho]

Still not cleaning up temp files after processing is done.

For a 6.8GB MKV I still get:

• 1 remaining 6GB MKV file in Temp\tempfreesubtitle\
• 2 remaining 2.25GB+2.25GB WAV files in Temp\htdemucs\

The program should do the clean-up after the task is completed. The 'Temp' folder is NOT a folder that Windows will delete or clean on its own.
