Fixes #128 - Change display of Admin login password expiry notices

For some reason, modern-day computer users don't understand the concept of "password expiration" as well as people accustomed to using client-server or mainframe systems, and thus tend to become paranoid at the concept of a password "expiring". They think they'll be locked out, rather than merely required to provide a new password on a scheduled cycle.

This commit simply removes the language causing the confusion. Less is more.
Request Class Issue #65

See also Pull requests #119

I've made the request class a first class object rather than use the static/facade interface used previously
That only really made sense if we had some DI container to manage it. Although given the use of some 'global' classes
in the code, the use of a DI container is looking more necessary. Something for the future.
I've also added codeception to composer and committed some basic start up stuff for that.
I think codeception looks better in terms of writing acceptance tests, over a selenium/sourcelabs framework.

pr #65 - Request Class - all method

I decided against either having the request class either implement IteratorAggregate itself or make the parameterBag an object in it's own right,
and implemeting an iterator in that class, and just return the parameterBag as an array object. ArrayObject implements IteratorAgrregate anyway.
