UI Changes first cut - Moved navbar and main to right, aligned them and
added margin. Removed fluid for "main", but still responsive aspects
remain for navbar, side menu and contents. Have to remove responsive.
Restore responsive removed in last commit while retaining center
positioning and width.
Change text color to original bacause text was appearing white!
Took out all changes in css done for center positioning to make code
compliant with default bootstrap navbar example (in test.html). I took
out jumbotron from default example and replaced with devoops "main" div.

Also tookout .navbar styling that was overriding default bootstrap
navbar style. Now style2_v2.css is almost same as it was originally
except for .navbar style.

Reason for ditching devoops index.html/navbar - 

devoops navbar wasn't responsive, i.e. it shrunk badly. And Dashboard
(main page) had scrollbar which could be removed by modifying devoops.js
but alignment with devoops navbar was getting messed up.
