Changes

tsk5 Adds support for capture the activation petitions
Adds a view for the account activation process and a ManagedBean for
this purpose. The view will get the user UUID from the URL and the
ActivationManagedBean will try to find the user by the URL UUID. If the
UUID is not in the database, the view will show an error. If the user is
found, the ActivationManagedBean will check if the user account is just
activated. If it is just activated, will nofity the user that the
account is just activated. Otherwise, will activate the accountand
notify to the user that the process finished correctly.
