tsk70 Adds and removes the user's profile of the user
Adds again the action to add a player profile. This action is accessed
as previosly from user edit. The add player view is reused to also add
the profile, passing as a parameter if you have to register a profile or
a player. It also incorporetes the action of deleting a player profile.
This profile is also shown in the list of players, with the options to
edit and delete. The deletion of the profile must be a physical 
deletion, if not the user can't add a profile again. However, the 
deletion from this view is logical. Therefore, it is verified that the
profile isn't deleted from these options, so only the profile can be
deleted from the edit user view.
