Changes to fix the session bug
Stripped keywordSearch.html of bootstrap for project 4. Commented out the unused code. Added a simple css file for styling of project 5 part B
Fixed the session bug by keeping track of all visited items with a buy price and sending the item ID to the requests for buying to verify against the session data.
Merge branch 'SessionBugFix'
Final commit for project 5
Forgot lib/ folder in the zip. Test fails otherwise lol
