Issue summary:
While using the Google Analytics Add On I realised that some (calculated) 
metrics give incorrect results or have problem with the number format:
ga:sessionDuration
ga:pageviewsPerSession
ga:avgSessionDuration

Steps to reproduce issue:
1. Install Google Analytics Add On
2. Configure ga:sessions, ga:sessionDuration, ga:pageviewsPerSession and 
ga:avgSessionDuration as metrics and ga:date as dimension. 
3. Go to report output

Expected output:
Date 1-8-2015
Session Duration 754    
Avg. Session Duration   27,92592593
Sessions 27

Actual results:
Date 1-8-2015
Session Duration 754.0  
Avg. Session Duration   27.925.925.925.925.900
Sessions 27

NOTE:
Session Duration should be 754 or 754,0 according tot my number format.
