Button Added to clear options below the time table

[Manvi07]

@arnav-t , Could you please elucidate on how you'd like to have it?

[arnav-t]

@Manvi07 Well for one the button should do something when it's clicked. It should:

• Be on the same row as the "Click on a slot..." text.
• Be stylized using bootstrap classes with an icon (e.g from Font Awesome).
• Most importantly, it should clear the timetable. The version included in the PR does nothing.
