Added register-admin route, reading json data from body

[dhananjaysingh10]

Issue #76

• Added register-admin route
• solved the problem, admin data saving multiple time in DB
• Saving password in encrypted form in DB
• earlier routes can not parse JSON data from due to one error in app.js file (faced this problem while testing, Now solved)
  I have improved my code, please let me no if there are some error. I will try my best to fix them.
  I have attached some of the screenshots
