Add in itree code field and update to eco.py 0.0.2

The big change in eco.py 0.0.2 is support for bulk eco benefits, so most
of the changes in this commit are related to reorganizing the
ecobenefits module to properly send data back and forth
PTM data corrupts this column, just fix it to a value

Add in itree code field and update to eco.py 0.0.2
Refactor ecobenefits views to avoid decorators

Similar to the treemap app, eco benefits now follows a schema
similar to:

```python
def benefits_for_tree(instance, tree_id):
    return ...

benefits_for_tree_view = json_api_call(
    instance_req(strip_req(benefits_for_tree)))
```
Add numpy for the eco.py library
Add SpeciesManager for filtering by both common_name and scientific_name
Add filtering and max_items to species endpoint, tests
Add tests for Species.scientific_name
Merge pull request #79 from ahinz/topic/eco-views

Refactor ecobenefits views to avoid decorators
Refactor tests for clarity
Modify SpeciesManager.conatins_name to first do a multi-tiered search

First contains_name will attempt to search based on the exact text entered,
then if that returns no results it will do a more complex search by
breaking the query string into words and searching for each individual word
in the various name fields.
Merge pull request #83 from maurizi/topic/testSpeciesScientificName

Add tests for Species.scientific_name
Initial API import from OTM1 (broken)
Add api app to OTM2
Remove compiler issues and warnings from tests

Baseline 'api.Version' is working

Also upgrade to Django 1.5 best practices
Create initial api shims in treemap views
Refactor api recent edits to work with audits
OTM2 searching and tiling have changed, remove the old stuff

In particular, the API no longer supports generating tiles,
nor does it support the old filtering style (including CQL).

OTM2 api-based apps should instead use Windshaft TMS with a
standard OTM2 json-based filter query string.
