/**
* This function is beign used to add a new user to the www database.
* it will first check if the sent $_POST variables are valid for registering, if one or more rules are broken (eg the username is too short) the template will be reloaded
* but this time with the appropriate error messages. If the checking was successful it will call the write_user() function (located in this same file). That function will create
* a new www user and matching ticket_user. It will also push the newly created user to the shard. In case the shard is offline, the new user will be temporary stored in the ams_querycache,
* waiting for the sync cron job to update it.
