Yet another style change to the filter tag buttons
Prevent errors when no X axis labels exist (would prefer there to also always be an X axis label, even with only one datapoint, but can't figure out how to do that)
Stubbed out custom query builder tray (commented out)
Correcting an issue with the tag cloud example where filtertags were not properly cleared. This was visible when reselecting the dataset and picking a new tag...old ones reappeared.
