3.1.5 - squished subfolder + folder picker fix

small one, two things:

• new: "Save to" can now send squished videos into a "squished" subfolder
  next to the originals, instead of mixing them in with the source files
• fixed: if you made a new folder in the picker and renamed it right away,
  Video Squisher could still save into the unrenamed "New folder". It now
  always uses the name you actually typed

3.1.4 - skip no longer trips up the next video

• fixed: skipping one video in a queue could make the NEXT video come up
  with an error. The cleanup that makes Stop and Skip instant was reaching
  into the next video's first moments of work. It stands down the moment
  the skip is done now, and never touches a newer run

3.1.3 - Stop and Skip are truly instant

• fixed: Stop and Skip are properly instant now. They used to wait out the
  current encode step, which could take a while on big files. Every ffmpeg
  process is stopped on the spot now
• new: clicking Skip shows "Skipping..." on the row right away, then
  "Skipped" once it's done
• new: click the status text of a finished, skipped or errored video to
  send it back through the squisher for another go
