wezterm: Add event handling

Added shell aliases for 'image listings' which aims to mimic the `ls`
command in a very simple way.

Invoke it via `il` to display a grid of all images residing in current
directory. Images are being detected not by their extension but by
running a `file` operation on, so in very large directories this might
take a little (though, your terminal will probably buckle under the
weight of displaying thousands of images anyway, so use with care).

`IL` provides the same functionality but recurses into an arbitrary
amount of subdirectories. Very useful to get an overview of a certain
directory and its children but, again, think for a second before using
since this could easily spew thousands of pictures into your term.
