Subject: [PATCH] Add First Script - Video Compression (#40)

* Script is working well. Maybe not its final resting place but adding it to the repo here for now.

* Add Signal to favorites after Delta Chat.

* Fix the a and v parameters never being used.

* New file to copy all scripts to /usr/local/bin/.

* Call the new file which installs everything under files/scripts/.
