Improve formatting of Distribution string representation. (#379)
Upgrade to Django 1.5. (#387)
Make a minor formatting fix.
Update some additional URL template tags for Django 1.5. (#387)
Fix some template includes after Django 1.5 upgrade. (#387)
Place a template include inline in the base template.

The include was failing for some reason under Django 1.5. Moving
these few lines into the base template has no effect on the
client code and should be equally maintainable. (#387)
Fix a failing test.
Remove obsolete, unused PUT and DELETE methods on Pile API calls.

This removes some pieces from early on in the development of the API
that are not needed, along with some now-failing tests. (#387)
Update another deprecated import for Django 1.5. (#387)
Disable species API-call caching due to mysterious Content-Length error.

Upon requesting a /species/{pile}/ API call a second time, the
response is supposed to come from our hard cache in api/views.py
(_species_cache). However, this produces an error in Chrome:
ERR_CONTENT_LENGTH_MISMATCH. Somehow the cached copy seems to
have a content length that is much smaller than the original
(5,401 vs. 88,002 for /api/species/lycophytes/). (#387)
