Improvements to order, product, checkout & added shipping (#2)

* planet_id variable casing consistent with database field

Renames all clientId variables to planet_id

* Store stripe json response from latest payment & charge webhook

Also added db seed file for stripe payments

* Image support! Can now add, update & delete images from products

Images moved away from product schema to it's own table.
Accepts a images string and relates it to a product. Does not store the
images or verify the existance.

* Instead of deleting a product set field unlisted to true

Endpoints with current inventory checks for unlisted = false

* order_id & customer_no gets enhanced base64 function for generating id

* Implemented shipping for orders using Post tracking api

Added CRUD for making changes to a order's shippment.
Split shipping table into shipment_courier, shipment & shipment_event.

* Updated and add product & product_sku functions updated

* Cart increment funciton checks stock before updating

* Endpoint for getting product audit log using 91pluss trigger

Read more about usage here: https://wiki.postgresql.org/wiki/Audit_trigger_91plus

* On stripe charge successfull send email to user with planetposen-mail

* More product seed data, linting & formatting

* Log file at /var/log/planetposen_logs & rotate max 3 files 100MB each

This will prob throw a error if folder does not exist, run: `(sudo)
mkdir -p /var/log/planetposen_logs`.

* All endpoints now prefixed with /api/v1

* Linting
