Task Creation Form

[leopiresgoss]

According to #25 , the create task form didn't use to handle the type of tasks when clicked.

To solve that, I:

• Refactored the handle change (input listener) to get this data when clicked and change its color
• Added handleSubmit to prepare when the API is ready
• Obs.: I also added ids and key to assign students page because it was throwing a warning
