Retabbed pom.xml file

We use 4-spaces instead of tabs in pom.xml. @smishra2's commit had tab
characters.
Reformatting of Jetty code to match guidelines

We have coding guidelines on the wiki:
<https://github.com/routemaster/routemaster-frontend/wiki/Coding-Guidelines>

My modifications were:

- Use spaces not tabs
- Use same-line curly braces (not explicitly in the guidelines, but in
  the code samples)
- Wrap to 80 columns
