Update to readme?

[Merith-TK]

So basically this is an update to the readme that i am requestion,
first, nitpicking

1. update gif to match new ui

Others

1. Extensions need to be mentioned that some extensions need you to cd ${extensionDir}/extension and then npm install them in order to work properly for some weird reason, (i have had to do this with the golang extension)
   i have made a bash script for this

#!/bin/bash

for dir in *; do
        if [[ -d $dir ]]; then
                pushd $dir
                npm install 
                popd
        fi
done

2. Elaborate on the "custom extensions" Why you guys have done this? what benefits are there rather than using the code-oss bindings stuff for the store? as far as i know everything is compatible

See #1014 regarding pt 1

The second issue is being dealt with as part of #1299

The last point is going to be handled tomorrow in #1333
