filtered out times from existing blocks. got division from conference listing, not from student's grade.
added a lot of stuff. switching out the submit area whenever the system is checking for duplicates and availability. browser compatibility fix, as IE8 and less doesn't recognize the 'change' event on a select menu. to still get the same effect I have just added a 'select' button to the right of each menu so that the user has to just click the button instead of changing the drop-down menu option. looking back this is probably actually the best option. added a bit of styling as well. need to get rid of any console.logs(), but otherwise it should be pretty browser compatible.
