Add a script for converting Newpipe to OPML

Browse Source 
This script uses Oil shell as an initial test for writing scripts with
Oil shell. I think it's a great starting example demonstrating the newer
features such as eggexes and the new formatting of the blocks (e.g., if
and while loops).

Also, updated some scripts lel.
