Processes added

Files added to put custom processes into, including events for:
load, login fail, login, logout and new user
Renamed template to config___template.php
New iframe added for processControl

Processes will be loaded into this. For now it's only used by
processes/on-load.php.
As more processes are added this will be used by them.
onLoad, run processes/on-load.php

open this in the new iFrame, processControl
Run processes on events

On logout event, include that process
Settings template file is now config___template.php
Create new if statement for login success and fail, plus run processes
for each event
On new user setup, run that process
If multiUser, always show the checkUpdates box as we don't know if we're
setting up a new user or logging in, so have to assume it's a new user
and allow this setting to show
