Local.java, StatefullLed.java:
-updated to use refresh interval in XmlFormatter

Coordinator.java:
-possibly fixed bug where drivers whose thread is in state BLOCKED or RUNNABLE would not terminate

Driver.java:
-removed call to notify() that should not have been there.

index.css:
-changed theme a bit
-settings page now uses same color for all section icons
