Inform the user that the link_id cannot be changed
Hide the extended help text once the user has created a profile,
since the link_id can no longer be changed.
Also moved the link_id to the top of the screen, to make it look
better when the extended help text is not shown.

indexes:
# AUTOGENERATED
# This index.yaml is automatically updated whenever the dev_appserver
# detects that a new type of query is run. If you want to manage the
# index.yaml file manually, remove the above marker line (the line
# saying "# AUTOGENERATED"). If you want to manage some indexes
# manually, move them above the marker line. The index.yaml file is
# automatically uploaded to the admin console when you next deploy
# your application using appcfg.py.
