OpenNMS Compass 3.0.1

Bug fixes and performance improvements. (Sorry, couldn't help ourselves.)

But seriously, this release contains just a few small changes:

• fix missing "Clear" button on the node search
• fix hidden search results when a user has scrolled and then the search shortens the list
• don't flash cached data on reload when there was an error
• show a spinner on the dashboard while network operations are still in-progress, even if cached data is shown
