225 profile edit

[Taks07]

• Changed profile page to make use of useAuthenticatedMember() hook to get profile details
• Member details can now be updated only by tier 3 admins or by the member themselves from the profile page
• The email field is disabled on the profile page (can't change), as the above is done by comparing the email with the jwt session in the server

closes #225
