Connect Vendor's Information on Purchase to Back End Database

[mckenzietsean]

148

NOTE: This is only part of #148, as only the vendor's data is ready at the moment. When their inventories are ready and purchase orders can be tracked, then the rest of the page can be connected.

Changes:

• Fixed VendorContact flux problems
• Connected VendorContact functions to the front end
• Vendors can be created, modified, and deleted from the database via the front end
• Changed address to be split into the street address, city, postal code, and province when modifying a vendor's data
• Phone numbers can now be properly loaded and modified without issues
• This includes saving phone numbers of newly created vendors as well
