Feat: Showing full name for proposers of projects, instead of username, where we have the full name. full name is stored in a new table, person. this has been mostly populated by an insert command in person.sql. the rest of the entries are for testing only. Additionally, behaviours have been implemented to hide the full name textbox in the front end for certain scenarios.
