added in sort buttons and adjust all filter

kinda ugly and janky but added in sort buttons on list… can’t believe i
forgot til now. i should change the default sort to alphabetical but
much for now

also haven’t yet tested since filters in general aren’t working/hooked
up, but if nothing is checked for majors or positions then assume all
are checked now uses programmatic values (instead of the hardcoded
names associated with my test data) - BUT UNTESTED
