Accounts to alter, delete, and save contact data

[Al3afifi]

Create a system to register/log in (store accounts on firebase) to allow for the following features at least (in order of descending importance)

• changing item data (probably going to use V1 of UUID to maintain original object)
• deleting items (maybe if a user logs in, their uploaded items last longer)
• saving contact info to each individual person
• maintaining chat logs
