Am/feature inactivity timeout

1. Better UX experience for when session ends due to inactivity

I want GovReady-Q to automatically navigate me to the login page instead of continuing to display in the browser window the previously loaded GovReady-Q page.

Timeout should probably be a system settings in the database.

I know this is done when:

The session times out due to inactivity
Activity is identified by no up or down movement or clicks within the page 
The time amount for timeout has to be an adjustable variable 
CMS settings 30 mins 
Once logged back in user redirects to  Home page 

2. Time Alert - Better UX experience for when session ends due to inactivity

As a GovReady user, when my session times out due to inactivity,
I want to receive an alert that my session was going to time out in 5 minutes.

So that I wont be logged out while still working on stuff. 

I know this is done when: 

The system will send a notification when there is a certain number of minutes of inactivity.  This number of minutes is configurable in environment deployment setting and by default is set to 20.
