Fix : Filters not taking affect on shared public dashboard links (v3) #411

[nagarjun063]

1. Filter applied in editor mode gets applied on Shared Dashboard Link
2. URL parameters added to the Shared Dashboard Link get applied to the charts in case the chart consists of a filter by similar column.
   ( idea here is to put a filter for certain column in editor, over-ride the same with parameters passed via url )
