Allow users to change username/email

[pinwheeeel]

Was wondering if there's a reason why this feature isn't implemented.
Users should be able to change their username/email when editing their account settings.
If this idea goes through, is a cooldown for changing username/email a good idea?

There isn't really any reason to allow people to change email as it has to be to be a tdsb email anyways, but as for username... It's supported by the API but-
