Dashboard reimplementation [MJ-902]

Completed:
- Displaying analytics data via company_id
- Reducing number of Solr queries

To do:
- Filtering by microsite 
I'm not fond of this solution. The referer may not be defined. If it is, it may not be a microsite. For instance, a log I have right now has www.educationjobsite.com, www.beyond.com, and www.jobdiagnosis.com as referers on different jobs.
