Improve names of RunCollection views

[ascheibe]

There are some minor glitches in the naming for the views:

• All views start with RunCollection except for variable impacts. This is some sort of smurf naming and should be removed.
• The names should not be camel case.
• The tabular and the data table view should get better names to make it more clear what they do:
  • Rename the data table view into Chart Aggregations
  • Rename the tabular view into Tables
