Ability for User to Search for Quotes by Author or Quote / Partial Quote

• As a user, I want to search for quotes by who said them
• As a user, I want to search for people by their quotes
• As a user, I want to be able to search by partial quote

Changes to make:

• Add search boxes for author and quote searches
• Create a regex testing file for checking user input is valid
• Display appropriate feedback to users depending on results
• Connect user search function to the database query function
• Display quotes nicely if found
• Write tests
