Probably fixed the issue where the extension stops recording. The chrome.tabs.query call was occasionally returning an empty array of tabs. Not entirely sure when there would be no active tab, but this fix will make it so that it ignores the times when this happens.
Minor updates to data clearing. Fixed redirects after clear data and added a note on the raw data page with instructions for clearing data.
Proposed change to hide the average time spent view until we fix the issues with it.
