Initial round of Sales Module ORM work by julesstp.

This is more or less still practice with git and these models will most
likely have further modifications made to them. My new models are in a folder
called julesstp within the models folder:
	- itemsite.json
	- price_schedules.json
	- customer_group.json
	- warehouse_info.json

	new file:   client/orm/models/julesstp/customer_group.json
	new file:   client/orm/models/julesstp/itemsite.json
	new file:   client/orm/models/julesstp/price_schedules.json
	new file:   client/orm/models/julesstp/warehouse_info.json
I took my new model out of the models root directory and put it in my julesstp directory.
