DS Campaign: Move query functions into inc file

[aaronschachter]

Open to discussion, but there are so many campaign query type functions in the dosomething_campaign.module. Thinking of adding a file like dosomething_campaign.query.inc or a similar name, to house all these functions here:

• [ ] _dosomething_campaign_get_recommended_base_query
• [ ] _dosomething_campaign_get_recommended_query_nids
• [ ] dosomething_campaign_get_recommended_published_nids
• [ ] dosomething_campaign_get_recommended_staff_pick_nids
• [ ] dosomething_campaign_get_recommended_nids_by_term
• [ ] dosomething_campaign_get_recommended_campaign_nids
• [ ] dosomething_campaign_get_staff_picks
• [ ] dosomething_campaign_get_scholarships

@weerd did this with reportbacks, it's much cleaner
