Prettier URLs

[haydnba]

urls in the browser should show the request url but not the file name ('/create-user' not 'createuser.html' e.g.)...

we can do this by sorting out the relations between filenames and request paths etc. and perhaps keeping the display files in a specific folder - views - to be handled a specific way by the router: views are different from static files / assets...

the router would need to use regex to call the proper html file from the views folder while allowing the request url displayed in the browser to remain without the file extension...
