Changing index.html style, added settings.html page
Coordinator.java:
-pretty formatting for sleep time

Preferences.java:
-added getPreferencesMap() to return a copy of the saved preferences

SimpleHttpServer.java:
-moved file reading to a separate function
-added handler for settings.html, file is generated from template.html + content of preferences map

XmlFormatter.java:
-added generateFullXml() to return full page xml (unimplemented)

template.html, index.css, main.js, index.inc:
-work on the page formatting, broke index.html into template.html and index.inc
-added link to settings.html
-removed links from the header since these will be automatically generated from the widget and full page xml
-still very much a work in progress
