As a non-LDAP user I want to change my profile data to keep my profile up-to-date.

• Above "Change Password" insert "Edit Profile" - but (like Password menu entry: only for non-LDAP users)
• Optionally - integrate this functionality in the "Change Password" dialog.
• Edit Profile dialog should allow editing of (see admin dialog "Register New User":
  - "Long Name"
  - "EMail Address"
• The dialogs are "pre-filled" with the current profile content strings
• Use existing RegExp to check the Mail address. Empty Mail address is not allowed
  see lib/helpers.js
• Empty "Long Name" is allowed
• It is not possible to edit profile data of other users (see "change password" functionality)
• Add some E2E tests (even "Change Password" would profit from an E2E test)
