Fix for #1826: CSV download throw an unexpected error

Had to crank this one out as Jesse is in the midst of doing some data analysis, and didn't want block him (but wanted to get him on our latest, cool code!)

Changes:

* Need to keep both paged and raw data (view uses paged, csv uses non-paged) (Note: this should be refactored, now that csv and html views are not nearly as aligned)
* Changed some variable names to make the distinction clear.
* Had to tweak some broken links on the zone management page.

@rtibbles Please review when you have time.  I've verified that the `facility_management` and `zone_management` views look proper, but the code can be cleaned.
