* master:
  Various changes to tidy up code and maximize vertical space for histograms.  Also, moved around code that hides/displays visual elements for stats based on events so that old stats don't show when user has selected a new reference or region.  Made some small changes to get tooltip working in various charts.
Point to production servers.

  Fix indentation
1. Use production servers.
2. Fix vcf header truncation by using Jon Anthony's code to read header in a more sensible fashion, just reading one line at a time until a records without leading # is encountered.
3. Refactored code that gets stats for local vcf file so that it is easy to capture streamed vcf (catInputServer) immediately after vcfstatsalive server is run.  That way, same regions of vcf file are streamed to catInputServer (for creating a file to debug a problem) as those streamed to vcfstatsAlive server.
4. Don't show the tooltip for the reference donut chart as it still is unreliable in terms of location and also shows when it shouldn't (when 'all' references are selected...)
Don't show tooltip for reference donut chart right now as it still is a bit buggy.
Don't outline the bars because the bar width calculation doesn't take the stroke width into account.  Also, use a darker color for the bars.
Use Jon Anthony's code to get vcf header, which uses a more sensible approach, reading one line at a time until a records with # in first position is encountered.  My code was trying to calculate the number of bytes of the header by using the linear index, which turned out to by shy of the length to grab the entire header, truncating the last header record.
