scripts: Add nsxiv-rifle script
Opens basically any path, local or remote in nsxiv.
Can take multiple paths to open all of them.

Additionally, alias whichever version of the image viewer is available
on the system as `iv`, using `nsxiv-rifle`, `nsxiv`, `sxiv` in order of
preference.

# Advanced nsxiv url opening script.
#
# Can open remote urls of individual images, galleries, and local files at the same time.
# Uses gallery-dl for remote gallery opening - so if gallery-dl can open it, so can nsxiv.
#
# Usage: simply add multiple urls/paths as arguments.
