Compatibility with Tripal 3

[laceysanderson]

The Tripal Download API needs very little to make it compatible with Tripal 3. Really, the only change needed should be to change the dependency from tripal_core to tripal, since the Jobs API is supposed to be backwards compatible.

It turns out there is currently a new feature which breaks backwards compatibility: tripal/tripal#280. While we wait on that discussion the following patch will allow the Download API to work with Tripal 3.
