student page update

search still doesn't work. no clue why.
Fixed notices in some prints.

Please note: unless enclosed in string literals, you must use string
literals to access array elements with strings (i.e. $user['type']
instead of $user[type]).
TARS.sql bugfix

hopefully, this version works
Added a UI for the new term page for staff accounts. Also, included a JS plugin for bootstrap upload buttons.
